"I've done this a hundred times so this is not dangerous." --- Sounds like Evel Knievel.

"This lead in here is the same as your mother's lead crystal." --- Kids wonder: 'What the heck is my mother's lead crystal?'

Quite apart from the obvious dangers, given how notoriously litigious people are in the USA I'm surprised that he even considered getting kids to do this.

Yeah the CRT was not discharged to Ground and the kid was struggling to pull the lead and cap out the back of the Crt and THEN he stuck something under the cap into the CRT to get it off ,,,, Must not of been in California ! the way the "teacher" just let the Gas out for the kids to breath .....I think he is a Trump supporter 1

Reminds me of this old US insurance ad cartoon, theme "You wouldn't do this"

Dark night. Out of gas. Guy has taken the petrol cap off and is peering into the tank by the light of a match. Dog, looking out from the back seat, looks (justifiably) terrified!

That teacher is a flip.

Back in the 70's when I was an apprentice my boss and I took a 21 inch non bonded tube to the tip amongst a pile of other stuff.
Foolishly I propped the tube face out and threw a rock at it from about 6 feet away.
It projected large chunks of glass straight at us, one large chunk landing on the bonnet of the car some feet behind us.
Somehow all the pieces missed me but one piece hit my bosses' shin and cut him through his jeans.
The loud bang stopped everyone at the tip as they looked at our stunned expressions.
From that moment on I had a healthy respect for CRT's, particularly non bonded ones.

Yes it works out at over 1,600 Kg pressing in on the faceplate alone. No wonder it goes bang!

I once had one go off in a customer's house, inside the TV. It almost demolished the cabinet. Fortunately no-one in the room at the time. Laminated safety glass contained most of it.

I had fun at the tip too, in the mid 70s. It was the time when everyone was ditching their B&W sets and buying colour ones.

To blow up a picture tube I would place it face down, and throw something at the sloping sides. Almost always blew up first go with the usual pop, tinkle, and cloud of small particles. However one particular tube let go with tremendous power, bombarding everyone in the vicinity (and their cars and trailers) with large amounts of shrapnel. I played innocent, looking around just like everyone else did.

Needless to say, I was a bit more careful after that.
