Hi!

Are you someone who loves to experiment and explore new things? Then this article is for you buddy. Here are 5 cool experiments for you to try out.

Prime warning: Do these experiments only with the help of your parents or Adults.

1. Baking Soda and Vinegar Volcano

Materials:

Baking soda, Vinegar, Food coloring, Dish soap, A small container.

Procedure:

1. Place the small container in the centre of a tray.

2. Fill the container with baking soda.

3. Add a few drops of food colouring and a squirt of dish soap.

4. Pour vinegar into the container and observe the reaction.

Concept:

This experiment demonstrates an acid - base reaction, producing carbon dioxide gas which causes the ‘eruption’ that you would have seen.

2. Invisible Ink with Lemon Juice

Materials:

Lemon, Water, Cotton swabs, White paper, A heat source (lamp or iron)

Procedure:

1. Squeeze lemon juice into a bowl and add a few drops of water.

2. Dip a cotton swab into the juice and write a message on the paper.

3. Allow the paper to dry.

4. Heat the paper gently with an iron box that is mildly heated to reveal the hidden message.

Concept:

Lemon juice oxidizes and turns brown when heated, making the writing visible.

3. Density Rainbow in a Glass

Materials:

Different liquids (honey, dish soap, water, vegetable oil, rubbing alcohol), Food coloring,  
A tall, clear glass.

Procedure:

1. Color each liquid with a different food colouring.

2. Slowly pour each liquid into the glass in layers, starting with the most dense (honey) at the bottom.

Concept:

Demonstrates the concept of density as different liquids have different densities and form distinct layers.

4. Egg in a Bottle

Materials:

A peeled hardboiled egg, A glass bottle with a narrow neck, Matches or a small piece of paper, Lighter.

Procedure:

1. Light a small piece of paper and drop it into the bottle.

2. Quickly place the egg on the bottle’s opening.

3. Watch as the egg is sucked into the bottle.

Concept:

Explains air pressure differences; the flame consumes oxygen, reducing pressure inside the bottle, and the higher external pressure pushes the egg in.

5. Static Electricity Dancing Paper

Materials:

Small pieces of paper,  A balloon.

Procedure:

1. Inflate the balloon and tie it off.

2. Rub the balloon on your hair or a wool sweater to create static electricity.

3. Hold the balloon close to the paper pieces and observe them ‘dance’ towards the balloon.

Concept:

Demonstrates static electricity and the attraction between oppositely charged objects.

These experiments are cool right but don't forget to ask for help from your parents, safety is important. Have fun and great learning...
