Jean Rosseau had said, "We should not teach children the sciences but give them a taste for them." How do we do that? With these 20 fun experiments! Oh, the joys—and the trials and tribulations—of being a parent! Other than being adorable, snuggly, and wild, kids are observant and curious. Although their curiosity makes them jam their fingers in electric sockets, their active imagination pushes them to think about things and figure them out. Since we've been spending more time indoors these days, teaching our kiddos various things through experiments can be a fun way to bond with them. Here are 20 science activities that kids can do at home and discover the Albert Einstein in them.

Magic milk
Teach your kids how to recreate Van Gogh’s The Starry Night with this surface tension experiment. Fill a bowl with milk and add a few drops of food coloring in it. You’ll see blobs of different colors starting to form. Dip a toothpick or a Q-tip in dish soap and swirl the food color blobs with it. The soap reacts with the fat in the milk and creates this marbling effect.

Egg in a bottle
With this experiment, you can teach your lil’ ones the basics of air pressure. Light a paper and drop it into a bottle before placing a hardboiled egg over the mouth. The imbalance in the air pressure will push the egg inside the bottle without crushing it. Don't forget to be right next to your kid when they're trying out this experiment, as it's a wee bit dangerous.

Anti-gravity magnets
Kids can learn about magnetism with this fun and simple experiment. All you need is a powerful magnet and some paperclips. Place the magnet on the back of your palm, and gently lower your palm towards the paperclips. The paperclips will stick to the dorsal side of your palm. If you remove the magnet, the clips will fall off. Ask your kids to give this experiment a whirl!

Magic ink
Sliced apples start to brown when they're left out in the open for about 15 minutes. This is caused by oxidation. If you want your kiddo to learn about this phenomenon the cool way, take some lemon juice and use it like paint to write a message on a piece of paper with a brush. Once the ink dries, hold the paper against a lamp to see the message. Spooky!

A moldy experiment
This weirdly fascinating experiment will teach your child the importance of sanitization. Pour some salt, vinegar, or other additives on three bread slices and seal them in a plastic bag. Handle the fourth slice only after you have washed your hands thoroughly with soap. In a few days, you'll notice mold growing on the three slices of bread gradually, while the fourth bread is slightly mold-free.

Walking water
Grab two glasses and fill one with water. Add a few drops of food coloring to the water and place the containers two inches apart. Take a strip of paper towel and place the ends in each glass. In an hour, you'll notice that the colored water has walked up the paper towel and filled the other container with water. This is caused by capillary action.

If you want to teach your child about density, this one’s for you. Water and oil don’t mix because oil is denser than water. You can demonstrate this by mixing a few drops of food color in oil and pouring this mixture into a bottle of water. Fizzy or aerated water will make this experiment more fun. The concoction will start to bubble up and begin to flow around. There you go—your kid now has a stunning lava lamp!

Self-inflating balloon
You might have tried this science experiment when you were in school yourself. This is a fun way to teach kids how acids and bases react. Pour a tablespoon of baking soda in a bottle filled with some vinegar. Secure the mouth of the bottle with a balloon and shake the bottle. The reaction will release carbon dioxide, causing the balloon to inflate on its own.

Fired up tea bag
Empty the contents of a tea bag and place it on a plate. Light it carefully with a matchstick or a lighter. The hollowed-out tea bag is so light that it will rise as soon as it catches fire. Spooky, right? This happens because hot air expands and is less dense than the air surrounding it, causing it to rise.

Instant ice
If your little one is a fan of Elsa from Frozen, they’ll definitely love this one. Teach your child the principles of supercooling with this experiment. Chill a bottle of water in a container with ice and salt. Remove the bottle gently from the container once it is icy cold. Slam it on a table, and you’ll notice ice crystals starting to form.

DIY sundial
This experiment is a fun way to teach your child how time is measured by the earth's revolution around the sun. You'll need a dowel, marker, and a paper plate to make a sundial. Place a dowel upright at the center of the plate and mark the line where it casts a shadow every hour. And there you go—your little one has a timekeeping device that they made!

Egg staining
Like our teeth, eggshells are also made from calcium. Eggshells can be used to demonstrate how sugary drinks can stain our teeth. Pour some juice in one cup and plain water in the other cup. Place an egg in each cup, and let them sit overnight. You'll notice that the egg submerged in the juice has stained. This will teach your kids the importance of brushing their teeth.

DIY barometer
Air pressure plays a huge role in determining the weather. Stretch a balloon over the mouth of an empty can. Place one end of the straw on the can and insert a pointer through the other end. Place a ruler next to your DIY barometer. Ask your kid to note down the readings every day as the balloon rises and sinks according to the change in weather.

If your kids are fascinated with the mini whirlpools in swimming pools, then you can teach them about the centripetal force with this fun experiment. Fill 3/4th of a bottle with water and pour some glitter in it. Put the lid back on and seal it tight. Turn the bottle upside down and move it quickly in a circular motion for 12–15 seconds to create a glittery vortex.

Magic candy
Your kiddos will love this trick! Pour some oil in a glass jar, and put a candy stick into the glass. The refraction of light will make it look like the candy is broken into half or the middle part has disappeared. To make the refraction look more evident, bend it, and put it inside the oil to see the bottom half of the candy resting flat on the surface.

Kids don’t mind getting messy. And what better way to learn about polymers than getting messy with glue and glow in the dark paint? Pour 2 oz of glow in the dark paint in 4 oz of school glue. Add your lil' one's favorite food color, along with half a cup of liquid starch. Mix everything together until it forms into this smushy slime.

If your kids are fascinated by clouds and rain, this is the perfect experiment to teach them about the water cycle. Fill a mason jar with water and cover the top with shaving cream foam. With a dropper, pour some blue water. Watch as your kids look in awe as the foam becomes too heavy to hold the water, and it starts to rain blue!

An egg without a shell
Place an egg in a glass jar and pour enough vinegar till the egg is completely submerged. Let it sit in the vinegar for a few days. The reaction of acetic acid present in vinegar with the calcium carbonate in the eggshell will dissolve the shell. See, we just gave you another way to peel your eggs!

Water bending
Brush your kid’s hair repeatedly with a comb, and hold the comb against a running tap. Your kid will be amazed to see water being pulled toward the comb. This happens when the water molecules interact with the static electricity generated due to friction between the comb and hair. This experiment can be done with a balloon as well.

Mini steamboat
Pierce a hole at the base of a bottle and insert a straw through the mouth. Pour some vinegar and baking soda and close the lid. Shake the bottle gently and put it in a tub filled with water. The carbon dioxide generated due to the reaction between the vinegar and baking soda will rush out from the straw, pushing the DIY boat forward.
