• Natural disasters are a calamity caused by nature.
  • There are different natural disasters that take place and have different causes and precautions.


EARTHQUAKES-  It is a sudden tremor caused due to deep movements inside the Earth’s surface. In this, the ground shakes and all the things on the ground shakes. There are certain precautions that have to be followed during an earthquake:-

  • Run out of the building immediately.
  • go out and stand on the higher grounds.
  • even after the earthquake is over don’t go to your building because there can be certain aftershocks.

technology on fastest computer

 The six fastest computers in the world

In November 2014, the top six supercomputers all run Linux, but that’s about the only thing they have in common.

Tianhe-2, aka Milky Way 2

A four-time winner, Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, once more took home the title as the world’s fastest computer, with a performance of 33.86 petaflops (quadrillions of calculations per second) on the Linpack benchmark.



At the Oak Ridge National Labs, where the United States pulled out the raw material for the first atomic bombs in World War II, is America’s fastest supercomputer: Titan.

Titan, made by Cray — yes, the first supercomputer company is still around — uses AMD 2.2GHz Opteron 6274 16C processors to deliver 17.6 petaflops. That may not be anywhere near as fast as Tianhe-2, but Titan does it with half the electrical power and only a fifth of the cores. In short, Titan may not be number one, but it does more with less.


The world’s third-fastest computer, Sequoia, is an IBM Blue Gene design. For a while, IBM ruled supercomputers with this architecture, but now, while close to the top, it’s not number one. IBM has plans to take the number one spot back by 2017.



RemembeK-Computerr when SPARC was an important processor and Solaris was a top operating system? Well, you might not, but I do. While Solaris doesn’t even have a spot on the Top 500 supercomputer list, SPARC, thanks to Japan’s K supercomputer,

Mira Blue Gene


The fifth-fasMira Blue Genetest computer in the world, Mira Blue Gene, is another IBM Blue Gene design.

With more than 786,000 1.6GHz Power BQC 16C cores, Mira, which works on a variety of modelling and simulation problems at the US’ Argonne National Laboratory, can hit a top speed of 8.6 petaflops. That’s not bad for a computer that hasn’t seen a significant update since 2012.

CSCS Piz Daint

Europe’s top supercomputer, CSCS Piz Daint, ranks number six overall. This computer, which is based in Lugano-Cornaredo, Switzerland, is a Cray design.

So far, it’s hit a high of 6.3 petaflops. That speed is generated by 2.6GHz Intel Xeon E5-2670 8C processors. These, in turn, are partnered by cK20x coprocessors. While related to the graphic coprocessors you use to speed through your video games with, these high-end processors are designed for top server math performanc

Light and shadow

Hi i am aprameya . I want to tell you about Light and shadow

Image result for Light and shadow

“Shadow is of the nature of darkness; reflected light (lume) is of the nature of the light source (luce); one
conceals and the other reveals. They are always associated and inseparable from all objects. But shadow
is a more powerful agent than light, for it can impede and entirely deprive bodies of their light, while light
can never entirely expel shadow from a body, that is, from an opaque body.”

Constableʼs emphasis on fleeting effects in the landscape, encapsulated in his ʻchiaroscuro of natureʼ, reminds us that darkness
embodies significant elements of time. Light advances and is impenetrable, but darkness is porous and deep; in twilight or even
in total darkness we search for the contours of shapes amid all the ambiguities, and this is a slow, and hence more obviously timebound
process. The ancient Greek writer, Plutarch, had already sensed the profound


Light Shadows and Reflection

What is light?
Light is produced by luminous objects, such as fires, electric lamps and stars like the Sun. The light that we can see is called
visible light
, but there is also light that we cannot see, including ultraviolet light and infrared .Image result for light and shadow


Natural disaster is a major adverse event resulting from natural processes of the Earth;examples include volcano eruption, earthquake, tsunamis, cyclone  and other geological processes.In turn, an earthquake under the water can also cause a tsunami, as the quake causes great waves by pushing large volumes of water to the surface. Tsunamis can also be caused by underwater volcanic eruptions. Volcanic eruptions are another natural disaster, and they are caused by magma escaping from inside the earth.Related image

  1. Volcano.

volcano is a hole in Earth’s surface through which magma (called lava when it reaches Earth’s surface), hot gases, ash, and rock fragments escape from deep inside the planet. The word volcano also is used to describe the cone of erupted material (lava and ash) that builds up around the opening.  The study of volcanoes is known as vocanology. According to frequency of erurption,volcanoes are of three types: active , dormant, and extinct volcanoes.

An active volcano is a volcano that has had at least one eruption during the past 10,000 years. An active volcano might be erupting or dormant. An erupting volcano is an active volcano that is having an eruption… A dormant   volcano is an active volcano that is not erupting, but supposed to erupt again.  The Ring of Fire is a string of volcanoes and sites of seismic activity, or earthquakes, around the edges of the Pacific Ocean. Roughly 90% of all earthquakes occur along the Ring of Fire, and the ring is dotted with 75% of all active volcanoes on Earth.

dormant volcano is one that has not erupted recently but is expected to do so again. Prior to its 1980 eruption, Mount St. Helens had been classified as dormant.  At present, there are about 600 volcanoes that have had known eruptions during recorded history, while about 50-70 volcanoes are active (erupting) each year. At any given time, there is an average of about 20 volcanoes that are erupting.

Image result for information about dormant volcanoes a List of extinct volcanos includes volcanos which scientists consider unlikely to erupt again. A volcano which has not erupted in the past 10,000 years is extinct. The extinct volcano no longer has a lava supply. … Whether a volcano is truly extinct is often difficult to determine.Active volcanoes have erupted recently. A dormant volcano isn’t erupting right now. But volcanologist expect it would erupt at any time. Extinct volcanoes haven’t erupted for ten thousand years and aren’t expected to erupt again.


An earthquake (or quakes, tremors) is shaking of the surface of earth, caused by sudden movement in the Earth’s crust. They can be extremely violent or cannot be felt by anyone.

Earthquakes are usually quite brief, but may repeat. They are the result of a sudden release of energy in the Earth’s crust. This creates seismic waves, which are waves of energy that travel through the Earth. The study of earthquakes is called seismology.[1]Seismology studies the frequency, type and size of earthquakes over a period of time.

There are large earthquakes and small earthquakes. Large earthquakes can take down buildings and cause death and injury. Earthquakes are measured using observations from seismometers. The magnitude of an earthquake, and the intensity of shaking, is usually reported on the Richter scale. On the scale, 3 or less is scarcely noticeable, and magnitude 7 (or more) causes damage over a wide area. The study of earthquakes is known as seismology.Related image 3. TIDAL WAVES


tidal wave is a regularly reoccurring shallow waterwave caused by effects of the gravitational interactions between the Sun, Moon, and Earth on the ocean. The term “tidal wave” is often used to refer to tsunamis; however, this reference is incorrect as tsunamis have nothing to do with tides.Tides are the rise and the fall of the sea levels caused by the combined effects of the gravitational forces exerted by the Moon and Sun and rotation of the Earth. … The Sun’s gravity fields pull the water up in our earth’s oceans, and that’s what makes waves.Algae are microscopic sea creatures. When billions of red algae form, or “bloom,” in the ocean, the waves and tides appear red. Finally, rip tides are not a tidal feature. Rip tides are strong ocean currents running Image result for before and after tidal waves

planetary science

Planetary science or, more rarely, planetology, is the scientific study of planets, moons, and planetary systems and the processes that form them.

Planetary scientists work to improve our understanding of the planets, satellites and smaller bodies in the solar system through:

  • Studying the atmospheres, surfaces and interiors of planets,
  • Understanding the origins of planets and the physical processes at work, and
  • Using radar to determine the physical characteristics of asteroids and to search for asteroids that may pose a hazard to Earth.

Planetary science applies the theories and methods of traditional disciplines such as astronomy, geology, physics, chemistry, and mathematics to the study of the origin, composition, and distribution of matter in planetary systems, especially the evolution and structure of planets and their natural satellites.

The term planetary science encompasses a whole range of studies involving a combination of earthsciences and astronomy. Sometimes known as planetology or planetary studies, these disciplines are concerned primarily with the geologic, geophysical, and geochemical properties of other planets. They also draw on areas of astronomy, such as cosmology, a fascinating discipline devoted to the study of the origin, structure, and evolution of the universe. As always when considering realms beyond our Earth, there are many surprises. Indeed, the more one learns about Earth’s relationship to the rest of the cosmos, the harder it is to say which is more intriguing: the many factors that make Earth different or the myriad ways that our home planet is just like the rest of the known universe.

travel around the world

travelling is the best thing that you should do to release your stress and not only that you can enjoy with your family and can have some time .so its really helpful n u should try it.thank you !


There are many ways of spending free time. One of them is travelling. Certainly, it has its pros and cons.
First advantage of travelling is visiting interesting places and meeting new people. It is connected with getting to know other cultures and traditions which is surely valuable. Secondly, it is usually said that journeys educate, so whilst travelling as well as exploration we can make our knowledge wider. Also we become more experienced and ready to cope with surrounding world if we learn something while being in journey. Furthermore, travelling is the best solution for those of us who suffer from boredom or want to get away from ?grey reality? and experience great adventure. Journeys give to people a little fun and also make dreams come true.
On the other hand, journeys has some crucial disadvantages. Firstly, costs of travelling are often quiet high for example travelling by plane, so naturally not everyone can afford. What is more, journeys especially foreign ones expose us to danger of disease or even death. Travelling can lead to fall ill and maybe then to expensive treatment or in case of fatal accident like for instance car and aerial one to death of many people. The next disadvantage is fatigue that occur while travelling. Most journeys last very long and it can make us feel tired.
To sum up, travelling is a very good way of spending time. It can educate, give impressions, nice memories and let make friends. However, in my opinion travelling in spite of its whole advantages, it should not be the only way to learn about the world.

super car lamborghini



The company was founded in 1963 by FerruccILamborghin

THE company produced a record 2,430 vehicles in 2008. Of this, nearly 1,800 were the best-selling car, the Gallardo, and just over 630 of them were the flagship model, the Murcielago (above). The Murcielago can go from 0 to 100 kmph in 3.4 seconds. It has a top speed of 340 kmph.


THE founder, Ferruccio Lamborghini, was fond of Ferraris, but found them too noisy for regular use. Once, Lamborghini realized that the clutch of his Ferrari was broken, and found that it was the same clutch he uses in his tractors. When he approached Ferrari for a replacement, the company told him he was a tractor maker and knew nothing about sports cars. Yeah, right.


LAMBORGHINH has topped the Murcielago with a new version, the Murcielago SV. SV stands for “Super Veloce”, meaning “super-fast”. It costs 300,000 euros.

FERRUCCIO Lamborghini chose the bull logo for Lamborghini because his sun sign was Taurus. The cars, too, are named after fighting bulls, such as the Miura, the Diablo, the Gallardo and the Murcielago.

25 Cool Science Experiments You Can Do From Home

Posted by , Updated on March 16, 2017


If you’re looking for some of the easiest, safest, and most fun science tricks that you can do at home, then we’re happy to inform you that you will be really pleased with today’s list. Science might appear boring and dull to most people, but in reality, it’s full of fascinating secrets and simple tricks that are a great way to help you enjoy chemistry and physics (definitely more than you did as a student). It’s true that you can learn a bunch of interesting scientific facts by experimenting with different materials that react in crazy ways. You’ll find a lot of experiments can be done using simple ingredients found around your house that you never thought could be utilized in these ways.

Basic materials can help you perform experiments that are simple, safe, and perfect for kids. For example, did you know that all you need to create your own mini “torpedo” is shampoo and a toothpick? Or that in order to make certain things disappear from the eye’s line of sight all you need is some vegetable oil, proper lighting, and glass? If you want to discover other simple but awesome experiments like these, you will have to read our 25 Cool Science Experiments You Can Do From Home. We promise you won’t regret it.


Turn water into wine

wineSource: YouTube, Image:

For this experiment, you’ll need:
– two shot glasses
– clear piece of plastic (slightly larger than the diameter of your shot glasses)
– water
– wine

Fill one shot glass with wine to the rim. Fill the other shot glass with water to the rim. Next, place the piece of clear plastic over the glass of water. Holding the piece of plastic and glass of water together, carefully flip it and place it on top of the wine glass (the piece of plastic will be in between). Slowly, slide the piece of plastic so that there is a small gap in both the water and wine glasses. Due to the different densities, wine will go up into the water glass as water goes down into the wine glass, effectively replacing each other.


Toothpick Torpedo

toothpicksSource: YouTube, Image:

For this experiment you’ll need:
– bowl of water
– shampoo
– toothpick with blunt end

Dab a little shampoo on the blunt end of a toothpick. Drop the toothpick in a bowl of water, and the toothpick will start moving in the direction the sharp end. Magic? Nope! You see, shampoo contains agents that reduce the surface tension of liquids. As the shampoo on the end of the toothpick dissolves, it reduces the water’s surface tension around it, thus releasing the water’s hold on that end of the toothpick. The water around the other end has surface tension, so it pulls the toothpick in that direction.


The Fireproof Balloon

BalloonSource: YouTube, Image:

For this experiment you’ll need:

– two balloons

– water

– candle

– matches

Inflate the first balloon and tie it shut. Place a quarter of a cup of water in the second balloon, then inflate it and tie it shut. Light a candle using the matches and hold it under the first balloon. Allow the flame to touch the balloon. What happens? The balloon pops. Now hold the second balloon (the one with water inside) over the candle. Allow the flame to touch the balloon. What happens? It doesn’t pop. Water soaks up the heat from the candle. As the water closest to the flame heats up, it rises and is replaced by cooler water. The cooler water then soaks up more heat and the process repeats itself.


Slow Motion Ball

For this experiment you’ll need:

– thick liquid, preferably honey

– heavy ball

– a sphere shaped container.

Place the heavy ball in the lower half of the sphere. Fill the lower half of the container with honey, a little more than half. Tip the bowl from side to side to watch the slow-motion movement of the ball.
Note: If you use too little or too much honey, it will affect the motion of the ball.


Make Slime With Glue and Borax

Tom Cruise slimedSource: YouTube, Image: YouTube

For this experiment you’ll need:

– Elmer’s glue

– Borax powder

– food coloring

– water

Are you one of those people who had way too much fun seeing Tom Cruise and Katy Perry (among many other celebrities) being “slimed” at the Kids Choice Awards? Yes? So, what if we told you that you can make your own slime with glue and Borax? All you’ve got to do is to grab a bowl and mix 1/2 cup glue with 1/2 cup water. Add some food coloring of your own choice if you want colored slime. Get another bowl and mix a teaspoon borax with one cup of water until the borax is dissolved. Add the glue mixture to the borax solution, stirring slowly until it’s the right consistency, and then get ready to make a mess of your friends with your own slime!


Salty Ice Experiment

salty iceSource: YouTube, Image:

For this experiment you’ll need:

– two glasses of water


Ask your friends or family why the ocean doesn’t freeze in the winter. If they don’t know, or even if they get do, try out this experiment. Fill two cups halfway with water. Add some salt to one and stir it. Place both cups in the freezer or outside if the temperature is below freezing. Which one freezes first? You’ll find that the salt in the water makes it harder to freeze. Depending on the amount of salt, saltwater may need to be twenty-five degrees colder than freshwater to freeze. This is one of the reasons salt is used to melt ice on sidewalks and streets. It’s also one of the reasons why the ocean doesn’t freeze when the weather gets cold.


Reading what’s inside an Envelope

brown envelopeSource: YouTube, Image:

For this experiment you’ll need:

-an envelope

-a black felt-tip pen

-a piece of dark construction paper/a page from a magazine

Usually you can’t read the writing inside an envelope because of the light reflected off the envelope’s white surface, but a tube blocks that reflected light so you see only the light coming through the envelope. Write a word with a black felt-tip pen on a white piece of paper. Place the paper in a brown envelope and insert that envelope into a white one. Get a piece of dark construction paper or tear a page from a magazine with print on both sides. Roll the paper into a four-inch tube. When you hold the tube against the envelope, you’ll be able to read the writing inside.


No-leak Magic Bag

pencils through water bagSource: YouTube, Image: YouTube

For this experiment you’ll need:

-a zip baggy



Fill the bag almost to the top. Zip it shut, and start sticking pencils through the bag. Sometimes a few drops will leak out, but overall, this is a simple yet impressive trick that will make your friends idolize you.


Water Fire Starter

fire starter water bottleSource: YouTube, Image:

For this experiment, you’ll need:

– a Pom bottle of water

– two sheets of paper

– a sunny day (a must)

Are you looking for unusual ways to start a fire? Well, if that’s the case, all you need is a Pom bottle filled with water and two sheets of paper. Next, fold the two sheets of paper in half, twice. Print or scribble a black mark on one of the sheets. Then just pray it’s a sunny day outside! If the sun is smiling at you, just hold the bottle near the paper, focusing the light of the sun on the black area of the paper. Once it starts to smoke and a hole begins to form, wrap the other sheet of paper around the smoking piece. Wave the papers through the air to feed oxygen to the spark and keep doing this until the paper catches on fire.


Make Liquid Art

milkSource: YouTube, Image:

For this experiment, you’ll need:

– dish soap

– milk

– food coloring

– a plate

If you want to impress your friends without trying too hard, all you have to do is mix some dish soap and milk together. This mix causes the surface tension of the milk to break down. Throw in different food coloring and create a trippy chemical reaction that will make a plate look like a Picasso painting.


Make Crystal Bubbles

crystal bubbleSource: YouTube, Image:, Photo by Paul VanDerWerf

For this experiment, you’ll need:

– dry ice

– hot water

– bubble mix

This is one of the easiest scientific tricks you can do, well if the weather is helping. When the temperature falls below freezing, it’s possible to freeze bubbles into crystals. No special preparation is required since all you need is some bubble mix and cold weather. However, there’s another, a little more complicated way to  make a giant dry ice bubble that resembles a crystal ball, filled with swirling fog. All you need for this project is dry ice, hot water, and bubble solution. Pour hot water into a bowl, add dry ice and smooth a film of bubble solution over the rim of the container. There you go!


Make a Tornado in a Bottle

bottlesSource: YouTube, Image:

For this experiment, you’ll need:

– a plastic bottle

– water

– dish-washing soap

– glitter

To make a tornado in a bottle, partially fill a plastic bottle with water, add a few drops of dish-washing soap, and add a bit of glitter before swirling the water around to make your tornado easier to see. Put the cap on tightly and turn the bottle upside down and hold it by the neck. Yep! What you will be seeing is a mini tornado you just created.



collapsing buildingsSource: YouTube, Image:

For this experiment, you’ll need:

– a deep pan

– sand

– water

– a mallet

This is a disaster-based experiment that simulates earthquakes. It shows what happens to sandy soils when an earthquake shakes them up. First, fill a deep pan with sand and put it on a table. Then pour in water to just below the surface of the sand. Wiggle one of the short ends of a brick into the wet sand so it stands up as a building would. Then, gently and repeatedly tap the side of the pan with a mallet and notice what happens to the sand and the brick. All you need to do is observe from there.


Keeping Water Separate

water and wineSource: YouTube, Image:

For this experiment, you’ll need:

– two identical glasses

– water

– two tablespoons of salt

– a few drops of food coloring

– a sheet of sturdy paper

Fill two identical glasses with water. Add two tablespoons of salt to one glass and stir well. Add a few drops of food coloring to the other glass. Cover the glass containing the colored water with a sheet of sturdy paper, turn it upside down, and place it on top of the glass containing the salt water. Gently pull the paper out from between the glasses. The colored water and the salt water will remain separate.

Homemade extraction of your own DNA

DNASource: YouTube, Image:

For this experiment, you’ll need:

– your saliva

– an empty glass

– a pinch of salt

– liquid soap

– some juice from a grapefruit

– a few drops of alcohol

The first step to doing this is spitting in a glass and adding a pinch of salt. Then add some liquid soap, juice from a grapefruit, and some drops of alcohol. Once you have everything in the glass, stir the mixture and the white mucous filaments you will see on top will be your DNA. See, the saliva contains cells that have DNA. The detergent is used to break down the membranes that protect the DNA and releases it into the mixture. The salt makes the DNA denature and precipitate, while the grapefruit juice neutralizes the proteins that could damage the DNA.


Liquid Stacking

liquid stackingSource: YouTube, Image: YouTube

For this experiment, you’ll need:

– a tall glass or bottle

– dish soap

– vegetable oil

– dark corn syrup

– rubbing alcohol

– water

– food coloring

The key for the success in this experiment is to pour the liquids (inside the bottle) in the right order. So, first make sure to add the dark corn syrup, then continue with the dish soap, next add food coloring to the water and pour it in with the bottle while it’s tilted, and add the vegetable oil (bottle still tilted). Finally, add food coloring to the alcohol and pour it in with the bottle tilted. Your friends will be impressed when all you have really done is to follow simple steps.


Egg through a Bottle

hard boiled eggSource: YouTube, Image:

For this experiment, you’ll need:

– a box of matches

– a  of paper

– a peeled hard-boiled egg

– an empty bottle with an opening slightly smaller than the diameter of the egg

With this very simple trick, you can impress even the most knowledgeable science geeks. Use a match to light the end of a of paper on fire. Lift the egg off the bottle, drop the paper inside with the flame down, and quickly replace the egg. Watch the egg wiggle a little in the mouth of the bottle and then get inside.


Invisible Bottle

Invisible BottleSource: YouTube, Image: YouTube

For this experiment, you’ll need:

– glycerin

– a glass

– a bottle (that will fit in the glass)

This trick might sound a little difficult to achieve, but it’s so simple really. All it takes is for you to fill both the glass and bottle with glycerin and place the bottle in the glass, and it will look like the bottle disappears. You will be feeling like Criss Angel during the process.


Create Magnetic Fluid

Magnetic FluidSource: YouTube, Image:

For this experiment, you’ll need:

– a magnet

– plastic wrap

– ferric oxide (in powder)

– a small container

– vegetable oil

A ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. In 1963, NASA’s Steve Papell invented ferrofluid as a liquid rocket fuel that could be drawn toward a pump inlet in a weightless environment by applying a magnetic field. It contains nano-scale particles of metal, which can become magnetized, and the good news is that if you mix oil, toner, and a magnet, you can create your own ferrofluid and harness the power of magnetism. How? Wrap your magnet in plastic wrap and push your tapes to the side. Collect the ferric oxide with the magnet and place the powder in a small container off to the side to dry. Once it’s dry, add the vegetable oil and then you will have your own ferrofluid!


Reversing Liquid

Reversing LiquidSource: YouTube, Image: YouTube

For this experiment, you’ll need:

– a big glass

– a smaller glass

– three mixing glasses

– corn syrup

– a few pipettes

– food coloring

– some clips

To begin this experiment, you must pour the corn syrup into the bigger glass and then place the smaller glass inside of the bigger glass. Next, you will have to attach the clips to prevent the smaller glass from moving side to side in the bigger glass. To continue, pour a small amount of corn syrup into the three mixing glasses and then add food coloring and stir. Fill each pipette with a different color, then add the colored corn syrup to your big glass. Turn the smaller glass carefully and watch the colors mix. Turn it back and watch them unmix while the magic “show” happens right in front of your eyes.


The Leidenfrost Effect

The Leidenfrost EffectSource: YouTube, Image: YouTube

For this experiment, you’ll need:

– a pan

– water

– a stove

The Leidenfrost effect might sound complicated (judging from its weird name), but in reality, this trick is as simple as it gets. Some of you might even wonder what this effect is all about; well, the Leidenfrost effect is a physical phenomenon in which a liquid, in near contact with a mass significantly hotter than the liquid’s boiling point, produces an insulating vapor layer keeping that liquid from boiling rapidly. Due to this “repulsive force,” a droplet hovers over the surface rather than making physical contact with it. So, how do you achieve this to impress your friends? All you have to do is to turn the heat on high for about four or five minutes and then just add the water.


Magic Water Barrier

magic water barrierSource: YouTube, Image: YouTube

For this experiment, you’ll need:

– two of the same glasses

– hot water and cold water

– food coloring

–  a piece of plastic
To begin with, and to make this trick work, pour some hot water in one glass, cold in the other glass, add food coloring, then place the plastic on top of the hot water glass. Turn the glass upside down, place it on top of the cold water glass, then carefully remove the plastic. Hot water is less dense than cold water, so it “floats” on top of the cold water and it looks like “magic” happens.


Cook an egg without heat

eggSource: YouTube, Image:

For this experiment, you’ll need:

– an egg

– a bowl with alcohol

Cooking an egg involves denaturing the proteins present in the yolk. This protein denaturation is normally achieved by exposure to heat (boiling or frying), but another way includes adding compounds such as alcohol that denature the proteins by interacting with them and altering their 3D structure. So, next time you want to cook an egg, place it in a bowl and add some alcohol. After a few minutes, you will see it slowly “cook.” However, we cannot guarantee it will be tasty.


Change the color of your flowers

For this experiment, you’ll need:

– flowers

– a glass with water

– colored ink

Normally, we water plants to keep them alive. Plants have a tube system, called xylem, that distributes water and nutrients to all parts of the plant. Using colored water we are able to see this tube system. Place the flower in a glass with water and colored ink. After a while, you will see the petals have colored ribs, or veins, of the same color of the ink you added. So if your flowers are dying, why not give them some color?


A Can that Can “Walk”

For this experiment, you’ll need:

– an empty aluminum can

– a balloon

– a tissue

Place an empty aluminum can on its side on the floor. up a balloon and tie a knot in the end. Rub a tissue back and forth on the balloon. When you put the balloon near the can, the can will start rolling toward the balloon. See, when you rub the balloon with a tissue, the balloon gets a negative electrical charge of several thousand volts. When you put the balloon near the can, electrostatic induction affects the molecules in the metal. The outside of the can gets a positive charge, so it is drawn toward the balloon and starts rolling in its direction.

Clash of Clans is an online multiplayer game in which players build a community (in the form of a clan), train troops, and attack other players to earn gold, elixir and Dark Elixir. There are four currencies or resources in the game.[3] Gold and elixir can be used to build and reload defenses that protect the player from other players’ attacks. Elixir and dark elixir are also used to train and upgrade troops and spells. Gems are the premium currency.[3] Attacks are rated on a three star scale and have a maximum timed length of three minutes.[3]

The game also features a pseudo-single player campaign in which the player can attack a series of fortified goblin villages[5] and earn gold and elixir. The game has 2 ‘builders’ by default, but the player can install more builders (maximum 5) by buying them at an increasing number of gems. Builders are important for upgrading any building. If all builders are busy upgrading a building, one has to either wait (if the player wants to upgrade a different building) for them to be free or complete another building’s upgrade using gems[6]


To earn and store gold and elixir, players must build gold mines and gold storages and elixir collectors and elixir storages, respectively. Elixir is used to train new troops, carry out research in the laboratory to upgrade troops, to re-load X-Bows (available from Town Hall 9), and to build and upgrade certain buildings, mostly pertaining to buildings used in attacking another player’s base. Gold is used to build defensive buildings and to upgrade the town hall, which allows access to more buildings and higher levels for existing buildings. At Town Hall 7, dark elixir becomes available; this type of elixir is used to train and upgrade dark elixir troops and heroes, create dark spells (available from Town Hall 8), and fuel the Inferno Tower, a defensive building that is available only at Town Hall 10. The Eagle Artillery, a defensive building only available at Town Hall 11, is fueled by elixir. Town Hall 11 also provides access to a new hero – The Grand Warden. It is the only hero born out of elixir. To earn and store dark elixir, players must build dark elixir drills and dark elixir storages.[7]

There are a number of buildings available to the player to defend their village, inclauding cannons, mortars, bombs, teslas, traps, archer towers, wizard towers, inferno towers and eagle artilleries. Players can also build walls, which can be upgraded as a player’s town hall level increases.

3.Troops And Spells

Image result for clash of clansThe game has two kinds of barracks (barracks and dark barracks) and two kinds of spell factories (spell factory and dark spell factory). The barracks create troops using elixir (Barbarian, Archer, Giant, Goblin, Wall Breaker, Balloon, Wizard, Healer, Dragon, P.E.K.K.A, Baby Dragon, and Miner) whereas dark barracks create troops using dark elixir. (Minion, Hog Rider, Valkyrie, Golem, Witch, Lava Hound, and Bowler)

The spell factories follow the same pattern – the normal spell factory creates spells using elixir (Lightning Spell, Heal Spell, Rage Spell, Jump Spell, Freeze Spell, and Clone Spell), and the dark spell factory using dark elixir (Poison Spell, Earthquake Spell, Haste Spell and Skeleton Spell). All troops and spells have different properties. As the player progresses, several new troops and spells are able to be unlocked.


Aside from the game’s resources (gold, elixir and dark elixir), the game also uses gems as a currency. Gems may be used primarily to finish the time that certain processes take, such as the remaining time of a building’s or a troop’s upgrade, or to instantly train an army. Additionally, they can be used to “boost” certain buildings, such as resource productions, heroes, and barracks. Gems may be acquired through in-app purchases, or they may be awarded for reaching certain milestones, completing achievements, or from clearing obstacles, such as trees, mushrooms or gem boxes, which spawn randomly on a player’s base. After the May 2017 update, players can get gems from the gem mine in the Builder’s Base at a very slow rate.

5.Clans AND Clan Wars

Clans are groups of players who join together to support each other, either materially (donating troops) or verbally (giving advice). Players can join clans once they rebuild the special Clan Castle building early on. A major component of the gameplay of Clash of Clans is clans facing off against one another in the “clan wars”. Clan leaders and co-leaders can begin wars against other clans. Each clan is then given one “preparation day” and one “war day.” When a player attacks a member of the opposing clan, they receive stars based upon the amount of destruction they cause to the opponent’s community. Each player is limited to two attacks per war, and the team with the most stars at the end of the war day is declared victorious. If the two clans’ number of stars are equal, then the victor is the one that has a greater percent of destruction. Players receive bonus war loot if he/she use their attacks in the war. This loot is different on different bases and is decided by Supercell; the top base has the most war bonus loot and the last base has the least amount of bonus loot. If the clan wins the war, the bonus loot is fully delivered to the player but during a loss one-third of the loot is delivered to the player. [14] In the March 2016 update, 35v35 and 45v45 were removed[15][16][17]. The available war sizes are 50v50, 40v40, 30v30, 25v25, 20v20, 15v15, 10v10 and 5v5[18][19][20]. In the May 2016 update, Friendly Challenges were introduced to allow clanmates to compete amongst other clanmates, however these challenges do not provide loot or trophies and do not affect a player’s army.

Cooking robot

Moley Robotics is a robotics company headquartered in LondonUnited Kingdom. It was founded by Mark Oleynik in 2015 to create service robots for kitchenuse.[1][2] It is best known for creating the first robot kitchen called The Moley Robotic Kitchen.[3][4][5]


Mark Oleynik, a computer scientist, founded the Moley Robotics in 2014 as a way to have good food at home without the skills to make it.[6] In 2015, Moley Robotics partnered started working on a robotic kitchen.[7] Subsequently, the company introduced its Robotic Kitchen. It made its debut at the Hannover Messe industrial robotics trade fair in Hannover, Germany in April 2015.[8]

The Robotic Kitchen has been distinguished in several international science and engineering events. In May 2015, the Robotic Kitchen won the “Best of the Best” CESShanghai award in China.[9] In January 2016, the prototype was finalist at the first edition of the UAE AI & Robotics Award in the international category, health sector.[10] The consumer version of the Robotic Kitchen is slated to launch in 2018.[11]

Robotic Kitchen[edit]

The current prototype of the Moley Robotic Kitchen includes two robotic arms with hands equipped with tactile sensors, an oven, an electric stove, a dishwasher and a touchscreenunit.[12][13] These artificial hands can pick up and interact with most kitchen equipment, such as blenderswhisks, knives and the hob.[14]

It captures, with an integrated 3D camera and wired glove, the entire work of a human chef and upload it into a database.[15] The chef’s actions are translated into digital movements using gesture recognition algorithms created in collaboration with Stanford University and Carnegie Mellon University professors.[16] Later, The Robotic Kitchen reproduces the whole sequence of actions to cook an identical meal from scratch.[17][18]

In the current prototype, the user operates the installation via a built-in touchscreen or smartphone application with cooking ingredients prepared in advance and put in preset locations.[19] Moley Robotic’s objective in the future is to enable the user to select from a library of over 2,000 recorded recipes.[20][21]
