I3-35: SOLAR BAG

Additional Info

  • ID Code: I3-35
  • Purpose: To demonstrate how the density of a gas changes with temperature.
  • Description: This is a large bag that will float when the air inside is heated. On a sunny but cool day, unroll the solar bag outside in the shade and fill it with cool air. Tie off the open end. Tie the string to the tied-off end, and move the bag into direct sunlight. The solar bag will soon float as the air inside heats up and expands. Obviously, this demonstration is primarily suited to outreach programs held out-of-doors, not to classroom use.
  • Availability: Available
  • Loc codes: I3
