Materials

  • 1 balloon
  • 1 candle
  • 1 wide tupper
  • 1 crystal glass
  • Water
Tip: Take the balloon out with great care of the tupper so that the glass does not fall.

Experiment for children: test the strength of a balloon

1. Fill a large water tupper and light a candle.

2. Heat the inside of a glass jar with the fire of the candle.

3. Place the glass on the opposite end of the balloon knot.

4. Put the glass in the tupper with water for a few seconds. If you carefully stretch the knot of the balloon, you will see how the glass has become attached like a suction cup.

The flame of the candle heats the glass and when covering the glass with the balloon the heat is maintained. When we introduce the glass into the water the pressure decreases and the balloon enters the glass holding on to it.
