My turn. Back in high school, one of my electronics teachers thought it
would be a good idea to teach us how to dismantle old TV sets for disposal.
We would remove the crts and break a small hole in the end of the neck,
to allow air into it to prevent it from imploding on some poor garbage man.

One team was to discharge and remove the crt, while I was armed with a pair
of pliers to let the air in. I approached one 26 inch colour tube they had
removed which was sitting face down on the bench. I placed my left hand
squarely on the back to steady it, and happened to brush the anode hole
with my right. I guess they forgot to discharge that one, because I saw
blue and black and was thrown back several feet onto the floor. I think
my arm was sore too, but my memory of the incident is fading...

For those that don't know, a picture tube is a big capacitor, capable of
storing charge for days. Watch it.

Dave
