Hi all; This is one of a couple of clips on-line showing safety demonstrations of what happens if you drain a tank without properly venting it. The hose was to drain the liquid contents of the thank.
Another one on YouTube is heating a 55 gal drum, sealing it and placing it on ice. After it cools to a point it suddenly implodes as well. Pieter E.
