When magnets attack

When I was a kid we used to buy dry ice from the local supermarket. We would take it home and drop a few ounces of the stuff into sealed two-liter bottles. Over the course of fifteen minutes the dry ice would sublime to carbon dioxide gas, causing the bottle to distend and eventually burst. Let me rephrase that – it would cause the bottle to distend and eventually explode.

Something like that happened to this MR scanner, only it involved liquid helium and was a lot more dangerous. Holy schnikes…
