20 Amazing Science Experiments to Do at Home

Science experiments aren’t just for classrooms—they can turn your home into a mini-laboratory of fun and discovery! Here are 20 hands-on experiments that are simple, safe, and packed with learning. Get ready to explore, create, and be amazed!

1. Baking Soda Volcano

Combine baking soda, vinegar, dish soap, and food coloring in a bottle to simulate a volcanic eruption. The fizzing reaction is caused by carbon dioxide gas release.

What You Need:

  • Baking soda
  • Vinegar
  • Dish soap
  • Food coloring
  • Small plastic bottle
  • Tray

Steps:

  1. Place the bottle in the center of the tray.
  2. Fill the bottle halfway with vinegar.
  3. Add a few drops of dish soap and food coloring.
  4. Pour in two tablespoons of baking soda and watch the “lava” erupt!

2. Rainbow in a Glass

Layer liquids like honey, dish soap, and water in a glass to create a rainbow. Each liquid’s density keeps them separate.

What You Need:

  • Sugar
  • Water
  • Food coloring
  • 4 glasses

Steps:

  1. Fill each glass with water.
  2. Add increasing amounts of sugar to each glass (e.g., 1 tsp, 2 tsp, 3 tsp, 4 tsp).
  3. Add different food coloring to each glass.
  4. Carefully layer the liquids in a single glass using a spoon. The denser liquid stays at the bottom, creating a rainbow.

3. Invisible Ink

Write with lemon juice on paper and reveal the message by heating it gently. The heat oxidizes the lemon juice, making it visible.

What You Need:

  • Lemon juice
  • Cotton swab
  • White paper
  • Lamp or candle

Steps:

  1. Dip the cotton swab into lemon juice and write a secret message on the paper.
  2. Let it dry completely.
  3. Hold the paper near a heat source to reveal the hidden message.

4. Dancing Raisins

Drop raisins in soda and watch them bounce due to carbon dioxide bubbles clinging to their surface.

What You Need:

  • Clear soda (like Sprite)
  • Raisins
  • Glass

Steps:

  1. Pour soda into the glass.
  2. Drop a few raisins into the soda.
  3. Watch as the bubbles attach to the raisins, causing them to rise and fall like they’re dancing!

5. DIY Lava Lamp

Mix oil, water, and food coloring in a jar. Add an effervescent tablet to create colorful bubbles that move up and down.

What You Need:

  • Clear bottle
  • Water
  • Oil
  • Food coloring
  • Alka-Seltzer tablets

Steps:

  1. Fill the bottle 2/3 with oil and 1/3 with water.
  2. Add a few drops of food coloring.
  3. Drop in an Alka-Seltzer tablet and watch the colorful blobs float and sink.

6. Magic Milk Experiment

Add drops of food coloring to milk and touch it with a soapy toothpick. The colors swirl due to the soap breaking surface tension.

What You Need:

  • Milk
  • Food coloring
  • Dish soap
  • Cotton swab

Steps:

  1. Pour milk into a shallow dish.
  2. Add drops of food coloring around the milk.
  3. Dip the cotton swab in dish soap and touch it to the milk. The colors will swirl and dance!

7. Balloon-Powered Car

Attach a balloon to a toy car and release the air to make it move. This demonstrates action and reaction.

What You Need:

  • Balloon
  • Straw
  • Tape
  • Lightweight car (made from cardboard or LEGO)

Steps:

  1. Tape the straw to the balloon.
  2. Attach the straw-balloon setup to the car.
  3. Blow up the balloon, pinch the end, and release it to power your car.

8. Egg in a Bottle

Add salt to water and place an egg in it. The egg floats because salt increases the water’s density.

What You Need:

  • Hard-boiled egg (peeled)
  • Glass bottle with a neck slightly smaller than the egg
  • Matches

Steps:

  1. Light a match and drop it into the bottle.
  2. Quickly place the egg on top of the bottle’s opening.
  3. The egg will get sucked into the bottle as the air inside cools.

9. Color-Changing Cabbage

Place white flowers in colored water. The petals change color as the plant absorbs the water.

What You Need:

  • Red cabbage
  • Blender
  • Water
  • Vinegar, baking soda, and lemon juice

Steps:

  1. Blend red cabbage with water to create cabbage juice.
  2. Pour the juice into separate glasses.
  3. Add vinegar, baking soda, or lemon juice to each glass and watch the colors change based on pH levels.

10. Homemade Slime

Mix glue, water, and borax to create stretchy slime. It’s a fun way to explore polymers.

What You Need:

  • Glue
  • Borax
  • Water
  • Food coloring

Steps:

  1. Mix 1/2 cup of glue with food coloring.
  2. Dissolve 1 tsp of borax in 1 cup of warm water.
  3. Slowly add the borax solution to the glue mixture, stirring until it turns into slime.

11. Static Electricity Butterflies

Rub a balloon on your hair and use it to pick up small paper pieces. This demonstrates static electricity.

What You Need:

  • Tissue paper
  • Balloon
  • Scissors

Steps:

  1. Cut a butterfly shape from tissue paper.
  2. Blow up a balloon and rub it on your hair to create static electricity.
  3. Hold the balloon close to the butterfly, and watch it “fly.”

12. DIY Compass

Magnetize a needle and float it on water using a cork. The needle aligns with Earth’s magnetic field.

What You Need:

  • Needle
  • Magnet
  • Cork
  • Bowl of water

Steps:

  1. Rub the needle on the magnet in one direction to magnetize it.
  2. Insert the needle into a small piece of cork.
  3. Float the cork in water, and the needle will point north.

13. Walking Water

Place jars of water with food coloring and paper towels between them. Watch the colors travel through the towels and mix.

What You Need:

  • 6 cups
  • Paper towels
  • Water
  • Food coloring

Steps:

  1. Fill 3 cups with water and add food coloring.
  2. Place the empty cups in between the colored ones.
  3. Fold paper towels and place one end in a full cup and the other in an empty one.
  4. Watch the water “walk” into the empty cups.

14. Water Bottle Rocket

Attach a balloon to a straw on a string and release it. The air escaping propels the balloon forward.

What You Need:

  • Plastic bottle
  • Vinegar
  • Baking soda
  • Cork

Steps:

  1. Fill the bottle with vinegar.
  2. Add baking soda to a tissue and wrap it up.

  • Dish soap
  • Small paper boat
  • Bowl of water

Steps:

  1. Float the paper boat in the water.
  2. Add a drop of dish soap at the back of the boat.
  3. The boat will move forward as the soap reduces surface tension.

16. Cloud in a Jar

Add hot water to a jar, spray aerosol, and cover with ice. A cloud forms as the warm air cools and condenses.

What You Need:

  • Jar
  • Warm water
  • Ice
  • Hairspray

Steps:
