Abstract

The familiar demonstration of collapsing a can by filling it with water vapor and then sealing it and allowing it to cool is improved by performing it with a 20-L steel solvent drum instead. This modification is significant because the steel drum is sufficiently sturdy to resist mechanical attempts to crush it. In contrast, the action of the atmosphere will dramatically collapse the drum almost completely.
