Learn this series of balloon experiments to teach your children to understand some of the basic principles of physics.

For this exercise you only need a balloon, some water and a microwave. It is important that you supervise the experiment to avoid any kind of mishap.

  • 1 balloon
  • Water
  • 1 microwave

Tip: Do not leave the balloon in the microwave for a long time because it will explode from the heat.

1. Take a balloon and pour some water inside it.

2. Tie a knot in the balloon so that the water does not leak out.

3. Put the balloon in the microwave and heat it for a few seconds. You will see how it swells little by little.

As the balloon heats up, the water evaporates. Steam increases the volume inside and as it is elastic, the balloon grows.
