i3-20a

  • ID Code: I3-20
  • Purpose: Demonstrate collapse of a can by atmospheric pressure.
  • Description: The air is removed from a large coffee can by a vacuum pump, as seen in the photograph above. The can is then given a strong smack with a large hard rubber mallet, causing it to unseat from the vacuum seal and to collapse with a rather large bang. The resultant coffee can is shown in the photograph at the right.
  • Availability: Temporarily Unavailable due to supply issues, we recommend I3-16 as a substitute
