CRT implosions

curt> I'll never seen anything horrendous in so far as implosions. I've seen one that was fairly spectacular. My father had an old TV CRT sitting around, from back in the separate glass shield days Tony mentioned. He carried it (carefully so as not to bump into things) to the car and took it to the dump. We set it out in the back of the dump, face down, stepped back 20 feet, and tossed bricks at it. We hit it where the neck joins the body. "Thud" sound and chunks of glass spread several feet. We were far enough away that it wasn't a hazard to us, and it certainly didn't spray bits as an explosion would. But it was sufficiently impressive that it taught me to handle all large glass vacuumm tubes with caution. Bumping into a stair rail and having it break in your hands would definitely be a Bad Day. paul
