5. Invisible Ink Messages

You need: Lemon juice, cotton swab, paper, candle or lamp.
Steps:

1. Dip cotton swab in lemon juice and write a message.

2. Let it dry, then warm the paper carefully over a light.
   What happens: Letters turn brown and appear.
   Learning: Heat causes oxidation.

6. Floating Egg

You need: Glass of water, salt, egg, spoon.
Steps:

1. Place egg in plain water (it sinks).

2. Add salt and stir until egg floats.
   Learning: Adding salt increases density, making the egg float.

7. Rainbow in a Glass

You need: Sugar, water, food coloring, spoons, cups.
Steps:

1. Mix sugar with colored water — one cup plain, one with 2 spoons sugar, one with 4.

2. Slowly layer them in one glass using a spoon.
   What happens: Colors stay in layers.
   Learning: Denser liquids sink; lighter ones float.

8. Soap-Powered Boat

You need: Cardboard, bowl of water, dish soap.
Steps:

1. Cut a small boat shape.

2. Put a drop of soap at the back edge.

3. Place on water.
   What happens: The boat zips forward.
   Learning: Soap reduces surface tension, creating movement.

9. Static Balloon Hair Trick

You need: Balloon, dry hair or wool cloth.
Steps:

1. Blow balloon and rub it on your hair.

2. Stick it to the wall.
   What happens: It stays stuck!
   Learning: Static electricity attracts surfaces.

10. Homemade Lava Lamp

You need: Bottle, oil, water, food coloring, fizzy tablet.
Steps:

1. Fill bottle ¾ with oil, add water until full.

2. Add food coloring and drop the tablet.
   What happens: Color bubbles move like lava.
   Learning: Oil and water don’t mix; gas lifts the liquid.

11. Walking Water

You need: 3 cups, tissue paper, food coloring, water.
Steps:

1. Fill two cups with colored water, leave one empty.

2. Fold tissues and place between cups.
   What happens: Water “walks” into the empty cup.
   Learning: Demonstrates capillary action.

12. Candle & Glass Vacuum

You need: Candle, plate, water, glass.
Steps:

1. Light candle on a plate with water.

2. Cover it with glass.
   What happens: Candle goes out; water rises.
   Learning: Air pressure drops when oxygen burns.

13. Paper Towel Strength Test

You need: Wet paper towel, coins, hanger.
Steps:

1. Hang wet towel between two supports.

2. Add coins until it breaks.
   Learning: Water weakens fibers and reduces strength.

14. Growing Salt Crystals

You need: Salt, hot water, jar, string, pencil.
Steps:

1. Dissolve salt in hot water until saturated.

2. Tie string to pencil and hang into jar.

3. Leave overnight.
   What happens: Crystals form on the string.
   Learning: Evaporation leads to crystallization.

15. Color-Changing Cabbage

You need: Red cabbage, water, vinegar, baking soda.
Steps:

1. Boil cabbage in water to make purple juice.

2. Pour into two cups. Add vinegar to one (pink), baking soda to other (green).
   Learning: Natural pH indicator shows acid or base.

16. Balloon Rocket

You need: Balloon, string, straw, tape.
Steps:

1. Thread straw through string and tie between two points.

2. Tape balloon to straw. Blow and release.
   Learning: Demonstrates Newton’s 3rd Law of Motion.

17. Homemade Compass

You need: Needle, magnet, cork, bowl of water.
Steps:

1. Rub needle on magnet 20 times in one direction.

2. Stick in cork and float on water.
   Learning: Magnetic field aligns needle to North-South.

18. Soap and Milk Colors

You need: Milk, food coloring, dish soap, cotton swab.
Steps:

1. Pour milk in a plate, add color drops.

2. Touch with soapy swab.
   What happens: Colors swirl beautifully.
   Learning: Soap breaks fat molecules in milk.

19. Sink or Float Test

You need: Bowl of water, small household objects.
