Fun with Pressure

Experiment #2 from Exploring Physical Science

Education Level
Middle School


The pressure of a gas is influenced by its volume, number of particles, and temperature. When you push a tire pump handle down, you increase pressure by decreasing the volume. You can increase the pressure in a bicycle tire by adding air particles. If an empty container of hair-spray is heated, the pressure may become dangerously high inside. In this contest, you will use a clean, dry container and what you know about gases in an attempt to produce the highest pressure.


  • Measure pressure.
  • Apply your knowledge of gases.
  • Have fun.
