Balloon on a Bottle

Main content

In this activity, students brainstorm various ways that an un-inflated balloon placed over a bottle's opening can be inflated without touching the balloon.

Learning Objectives

  • Students learn that air's volume changes with temperature
  • Students learn that air can both expand and contract depending on whether its temperature increases or decreases
  • Students learn that warming air increases the volume inside a balloon, no matter whether the balloon is pointing upwards, to the side, or downwards.
