Notice how I said "the glass face from an old tube" and not the whole tube.

You know, we always hear this, but I can't really decide how much is just
hype and FUD. The word "bomb" tends to conjure up firey explosions and the
thought of losing limbs when it goes off. (Actually, the dictionary
definition hinges on "explosion" and not an implosion like a CRT.) Every
CRT I've cracked, shot, and generally broken hasn't done much more than spit
some broken glass a few feet in a most anti-climactic manner. I've dropped
glasses in the kitchen with more spectacular results!
Anyone here *tried* to break the front face of an old 19" monitor with a
hammer? (I have. ;-) They're remarkably tough. Newer ones probably use
thinner glass (and flatter faces) and are more damage prone though. (An old
Sony 19" TV I had actually took about 5 .22 rimfire slugs from ~15 feet
before finally puncturing with a wimpy "ssssssssss" noise.) Knocking the
end of a tube with a hammer makes an interesting "foomp", and I wouldn't
want to be holding it when it did, but I don't find it too menacing. I
think the real risk is *dropping* a tube so that it shatters on impact.
That could be pretty dangerous from the flying glass perspective (but then,
so would be dropping a plate-glass window, or a big glass vase).
Anyway, just my $0.02.
