4E10.40-Hot Air Balloon

Description: Hot air rises!


  • Large, thin plastic bag
  • Wire circle of approximately 6 inches diameter
  • Hair dryer

Setup Procedure:

  1. If it hasn’t already been done, make a circle of the piece of wire.
  2. Staple the bag to the wire by folding the bag edges around the wire and stapling above. Make sure this is done uniformly around the bag.

Demonstration Procedure:

  1. Have someone else hold the bag for you (it’s MUCH easier this way).
  2. Blow hot air into the bag for about 30 seconds, being careful not to MELT the bag!
  3. Let go, and watch the bag float!
