If you want to perform this experiment for children you only need a balloon and freeze an empty glass bottle. With this fun science exercise your children will understand why a balloon can swell with a simple change in temperature.

Science experiments for children will help young children understand the basics of physics, which is an easy and fun way to learn.

Materials

  • 1 balloon
  • 1 bottle of frozen glass
Tip: The bottle must be empty, because if it contains any liquid frozen inside the balloon will not inflate.

How to inflate a balloon with a cold bottle, step by step

1. Take an empty glass bottle and freeze it.

2. Place a balloon in the mouth of the bottle.

3. Surround the bottle with your hand to warm it up. Little by little you will see how the balloon is inflated.

By surrounding the bottle bon hand the air inside the bottle, which causes the pressure increases with temperature and the air expands to the inside of the balloon.
