Most Amazing Scientific Experiment You can Do at HOME
From creating your own tornado to having clouds in a jar, This top 10 list of life hacks is awesome because you can DIY, even for kids! Try these cool science projects yourself and be a scientist! (You Surely Don’t wanna miss No.1)
10. Invisible Ink
Who hasn’t pretended as kids to be a spy or investigator? Well, now you can make your own invisible ink. All you’ll need are Q-tips, blank sheets of paper, and lemon juice poured into little bowls. Dip the Q-tips into the bowls and use them like pens to write messages or draw pictures on the paper. Once you’re done, let the papers dry. To reveal the secrets on the page, you will need to heat the lemon juice. This can be done using an iron but using a candle is way more fun! Light the candle and hold the paper above the flame. Don’t let it touch the fire or your message will go up in smoke. As the lemon juice warms, it turns brown, and the message or drawing appears. Be patient as this method takes a little longer than using an iron. The science here is pretty simple. When heated, the carbon compounds in the juice breaks down and produces carbon, which is black or brown.

9. Citric Acid Eruptions
For this experiment, you’ll need clear hand soap, warm water, food coloring, citric acid, and baking soda. You could use lemon juice instead of citric acid but the eruption won’t be quite as dramatic. In small bowls, mix the hand soap, warm water, and food coloring. You can do as many bowls as you want! Then, add two tablespoons of baking soda and mix. Finally, you can add two tablespoons of the citric acid or lemon juice. You may have to adjust the amounts to get a full explosion but the end result should be pretty amazing! The reason for the reaction is because when baking soda and an acid are combined, they create carbon dioxide.
This is called an acid-base reaction. Who knew chemistry could be so fun?
8. Make an Electromagnet
To do this, you will need a large iron nail, about three inches, three feet of thinly coated copper wire, a fresh D battery, and some small paper clips or other metal objects. Take the metal nail and wrap it with the wire. Leave about 8 inches of wire loose at both ends and try not to overlap the wires. You may have to cut the wire. Now, remove about an inch of the plastic coating from both ends of the wire. Attach one wire to one end of the D battery and the other wire to the other end. It is best to tape the wires onto the battery but
be careful. The wire could get very hot. You now have an electromagnet! Put the point of the nail near a few paper clips; it should pick them up. This magnet will use up the battery quickly, which is why the battery may get warm. Be sure to disconnect the wires when you are done exploring. Most magnets, like the ones on
many refrigerators, cannot be deactivated. These are permanent magnets. Magnets like the one you made that can be turned on and off are called electromagnets because they are only magnetic when the electricity is flowing. The electricity flowing through the wire arranges the molecules in the nail so that they are attracted to certain metals. To make it a real experiment, try to affect the strength of the nail by increasing the number of times you wrap the wire around the nail. Or, you can try thicker and thinner nails or thicker and thinner wire. The possibilities are endless.
7. Freeze a Bottle Instantly
For this experiment, all you need is an unopened bottle of purified water, a freezer, and a piece of ice. Place the bottle in the freezer for a little less than 3 hours. This will chill the water but because it’s purified, it won’t freeze. Take the super-cooled water and pour it over the ice cube. The purified water will freeze instantly. In order for water to become ice, it needs a nucleus in order for solid crystals to form. Usually, water is loaded with particles and impurities that enables ice to form. But purified water doesn’t have those particles or impurities because, well, it’s purified! This is why purified water can reach an even colder temperature before becoming solid. When you pour this super-cooled water onto a piece of ice, it provides the water with nuclei, causing it to freeze instantly. Now that’s a neat party trick.
6. Mentos in Coke
You may have already done this yourself but for those who want to try it, You’ll need one bottle of Cola (diet works best), one bottle of lemonade, one packet of mint Mentos, and an outdoor area you can hose down or completely avoid afterwards. it’s a simple and easy Trick: drop a mentos into a bottle of Diet Coke or lemonade and the soda will erupt from the bottle in geyser. You will probably notice it works best with Diet Coke. There are several explanations on how this experiment works: One is that a bottle of soda is full of Carbon dioxide bubbles. These bubbles stay suspended in the liquid until the bottle is opened, wherein the carbon dioxide tries to escape. When you drop any sort of object into a bottle of soda, bubbles form on the surface of the object. This is called “nucleation.” The surface of mentos is made up of lots of tiny craters. These tiny pits create a large surface area and essentially provide many more “nucleation sites.” The mentos drops onto the bottom of the bottle, forming lots and lots of bubbles on it’s pitted surface along the way. When all of this gas is released it forces the liquid up and out of the bottle in a giant whooshing geyser of sticking soda. However, no one knows why diet coke works best. Do You Know?

5. Dancing Oobleck
Inspired by a Dr. Seuss book, Oobleck is a non-Newtonian liquid. That is, it’s neither a solid or a liquid but is pressure-dependent. If you tap it quickly, a bowl of Oobleck feels hard. However if you slightly dip you hand into it, it will slide over your fingers like water. This amazing substance is made by combining cornstarch and water, with some food coloring thrown in for FUN. But did you know you can make Oobleck dance? First, you’ll need to make the Oobleck thicker than normal by combining two cups of corn starch with one cup of water. Secondly, you’ll have to get food coloring, a cookie sheet, an MP3 of an audio test tone, and a subwoofer. Place the cookie sheet onto the speaker of the sub, and pour in the Oobleck. To make the Oobleck dance, turn the volume way up and use 40 Hz, 50 Hz, or 63 Hz tone. Feel free to play with volume and hertz levels. The Oobleck should jump and dance with the vibration from the subwoofer. You may have to dig a finger in the Oobleck to get the movement started. Adding food coloring onto the top of Oobleck makes for a wonderful display.

4. Tea Bag Rocket
Here’s a fun experiment involving convection currents. take an unused tea bag and empty it of it’s contents. you can empty a tea bag by removing the staple and unfolding it or by cutting as shown in the slide show below. open it up so that it will stand upright, as a cylinder. Light the top of it on fire with a match or lighter and, as it burns down, it will suddenly shoot into the air. Hot air rises and this experiment demonstrates that idea as well as the principles of convection currents. As the tea bag burns, hot air is being created, as well as a thermal, or convection current, under the bag. When the tea bag burns down into a small enough ball ashes, the convection current causes it to shoot up in the air.

3. Walking on Eggs
Did you know that you can actually walk on EGGS without breaking them? Eggs are amazingly strong, despite their reputation for being so fragile. If you want to try to stand on eggs, you need to buy 2 cartons. If you’re feeling up to the walking on eggshells challenge, pick up 6-8 dozen eggs. spread a plastic trash bag (or bags) out on the floor and arrange the egg cartons into 2 rows on top of them. It’s really important that eggs stay in their cartons! Inspect all of the eggs to make sure there is no breaks or fractures in any of the eggshells. Make sure all of the eggs are oriented the same way inside the carton. One end of the egg is more pointy while the other is more round. So just make sure that all of the pointy or round ends of the eggs are pointed in the same direction. This is so your foot will have more level surface on which to stand. Remove your shoes and socks. Have someone to help you step onto the first carton of eggs. Keep your foot as flat as possible in order to distribute your weight evenly across the tops of the eggs. When your foot is properly positioned, slowly shift all of your weight onto to the egg-leg as you position your other foot on top of the second carton of eggs. Take your time! There will be creaking sounds coming from the egg carton, but don’t get nervous. go ahead and step forward and put all of your weight on the eggs. How is this possible? It’s the shape of the egg! Eggs are similar in shape of a 3-dimensional arch, one of the strongest architectural forms. the egg is strongest at the top and the bottom (or at the highest point of the arch). The egg won’t break when you apply pressure evenly to both ends. The curved form of the shells helps to distribute pressure evenly all over the shell rather than concentrating it at any one point. All of the credit doesn’t go towards the eggs, though. The carton plays a role in keeping them from breaking. Joseph Coyle is credited as the inventor of the first container made specifically to keep eggs from breaking as they were transported from the local farm to the store. As the story goes, Coyle invented the egg carton in 1911 as a way to solve a dispute between a farmer and a hotel operator who blamed the farmer for delivering broken eggs. Coyle designed a container made out of thick paper with individual divots that supported each egg from the bottom while keeping the eggs separated from one another. As legend has it, the fully loaded egg carton can even be dropped, and if it lands just right, the eggs will survive the fall.

2. Tornado in a bottle
You can create your own tornado in a bottle. One method is to use a single bottle but in this experiment, you use 2-two liter bottles. you will also need a washer, duct tape and water. fill one bottle with water and place the metal washer on top. tape the bottles together, mouth-to-mouth, with the washer in between. Duct tape is the best to use in this experiment because of how well it holds. You could also try to make a tube to hold the bottles together. Turn the bottles so that the one with water is on top and whirl it. When you whirl the liquid in the top bottle, it creates a vortex as it drains into the bottom bottle. That’s because as the water flows down, air must flow up, creating a spiraling tornado. You can even add glitter, food color, or lamp oil to the bottle to make the tornado even cooler.
1. Make a Cloud in a Bottle.
To make a cloud in a bottle, you will need a one gallon size glass jar, matches, a rubber glove, a rubber band, flashlight or lamp, food coloring, and water. Pour boiling water into the jar, just enough water to cover the bottom of the jar. Swirl the water around inside the jar so that it covers the sides. The idea is for there to be some water to evaporate. Put the rubber glove wrist around the mouth of the jar with the fingers pointing downward inside of it. this will seal all the air inside the jar. Try putting your hand in the glove. Once your hand is in the glove, move it upward so that you pull the fingers of the glove up. You’ll notice that nothing happens to the water in the jar. Light a match and drop it in the jar. stretch the glove back over the jar, with the fingers pointing down. The water at the bottom of the jar will put out the match, and smoke will form inside the jar. Slide your hand into the glove and pull it outward again. This time, a cloud will form in the jar. When you put your hand back inside the jar, the cloud will disappear. This will last for 5-10 minutes, and then the particles will settle into the bottom. Before the particles settle, shine a flashlight on the jar so you can see the clouds better. What’s happening? The air is full of warm water vapor molecules inside the jar. The glove compresses the air because the glove takes up some of the space inside the jar. pulling the glove fingers out of the jar releases some space in the jar and the air cools. The smoke from the match acts as a vehicle to which the water molecules can attach. They stick to the smoke particles, condensing into cloud droplets. When the glove fingers go back in to the jar, the air inside the jar warms up again and the cloud disappears. If you want colored clouds, add a few drops of food coloring to the water in the bottom of the jar before adding the match.
