Anyone hear the old myth that a CRT could implode if damaged?

It's a lot easier to break the neck of a CRT than the faceplate. If you break the neck all you get is a rush of air. No implosion.

All later CRTs (mid 1960s onwards?) have a tensioned steel band round the rim. This counteracts the pressure on the faceplate. If you smash the faceplate (and it will take a lot of abuse before it breaks) no glass should fly more than a foot or so in front of the set.

I wouldn't want to try this myself unless I was well out of any possible harm's way!
