Science Behind It

Dish soap breaks down fat molecules in milk, creating movement that pushes the colours around.

3. Invisible Ink Experiment

What You'll Learn

This activity teaches oxidation and heat reactions.

Materials Needed

• Lemon juice
• Cotton swab
• White paper
• Lamp or warm iron

Steps

1. Dip the cotton swab in lemon juice.
2. Write a secret message on paper.
3. Let it dry completely.
4. Heat the paper carefully under a lamp.

Result

The hidden message appears brown.

Science Behind It

Heat causes the lemon juice compounds to oxidise faster, revealing the writing.

4. Homemade Slime Experiment

What You'll Learn

Kids explore polymers and material science.

Materials Needed

• White glue
• Baking soda
• Contact lens solution

Steps

1. Mix glue and baking soda.
2. Add contact lens solution slowly.
3. Stir until slime forms.

Science Behind It

The ingredients form long polymer chains, giving slime its stretchy texture.

5. Colour-Changing Cabbage Indicator

What You'll Learn

This experiment introduces pH indicators.

Materials Needed

• Red cabbage
• Warm water
• Lemon juice
• Baking soda solution

Steps

1. Blend cabbage with warm water.
2. Strain the purple liquid.
3. Add different liquids to test color changes.

Result

• Acidic liquids turn pink/red
• Basic liquids turn green/blue

Science Behind It

Natural pigments in cabbage react differently depending on acidity or alkalinity.

6. Dancing Raisins Experiment

What You'll Learn

Children learn about gas formation and density.

Materials Needed

• Clear soda
• Raisins
• Transparent glass

Steps

1. Pour soda into a glass.
2. Add raisins.
3. Observe carefully.

Result

Raisins move up and down like they are dancing.

Science Behind It

Carbon dioxide bubbles stick to raisins, lifting them upward before they sink again.

7. Homemade Crystal Formation

What You'll Learn

Kids observe crystal growth and evaporation.

Materials Needed

• Salt or sugar
• Warm water
• Jar
• String

Steps

1. Dissolve salt in warm water until saturated.
2. Suspend a string in the solution.
3. Leave undisturbed for several days.

Result

Crystals begin forming on the string.

Science Behind It

As water evaporates, dissolved particles join together to create crystals.

8. Balloon Inflation Without Blowing

What You'll Learn

This experiment demonstrates gas production.

Materials Needed

• Balloon
• Vinegar
• Baking soda
• Bottle

Steps

1. Fill a balloon with baking soda.
