Description: Crush the can using the principles of thermodynamics.


  • Metal can filled with 1.5cm water
  • Bunsen burner, stand, and matches
  • Vacuum grease
  • Protective gloves
  • LN2 or cold water (optional)

Setup Procedure:

  1. Connect the Bunsen burner to the gas line and put the stand over the burner.
  2. Fill the can with about 1.5cm of water.
  3. Put a little vacuum grease on the can cover (to make an air tight seal when you cap it).

Demonstration Procedure:

  1. Put the can on the stand with the cap off and light the burner.
  2. Wait until a steady amount of steam is boiling off. (may take 10-20 minutes)
  3. Turn the flame off, and cover the can with the cap tightly (use protective gloves)
  4. You can either let it cool off slowly, or pour some LN2 or cold water over it (LN2 or water are more effective and faster).
