I read this yesterday, and I can't find the book now, someone else has it.
That theres a 17Lbs per square inch of pressure (vacuum, the pressure is from the outside) in a TV screen.
That works out to be over a TON of pressure over the whole TV screen!!!
Now playing around with a ton of pressure is pretty dangerous....
Just because its vacuum dosn't mean its all going in a inwards direction, it means its like crushing a lemon, some goes in, some squirts out.
Considering the glass is about a inch thick on the front screen, the shards are 3-4 inches long, tapered to a point 7 fly in every direction & theres a LOT of force involved.
Just imagine what would happen if you put a small amount of dynamite (one ton of pressures worth) inside the screen & let it go bang, thats just whats happening with the vacuum...
On a side note, where I have been scrapping for a while, I consider it 'my spot', TV's get dumped off.
A fat kid on a bike went past a couple of weeks ago, asked what I was doing.
I told him, & warned him about the TV screen & their propensity to explode.
So next time I go there, theres TV bits everywhere, cases, boards screens, just all ripped apart & the yokes & degaussing cables gone.
I figure its him, he's made a **** mess of the place & never cleaned up, didn't rip the boards, just the easy stuff, probably cost me $50.
So I clean it up a bit.
Next thing he arrives, gives me a story about "Someone who's watching this place & not to scrap there again".
Bull$h!t I think, next he starts undoing my cleaning up, probably thinking its all new TV's.
I say "Some dikhed made a real mess here & they are gonna put in a CCTV security system in now because of that. & not to muck around with the screens as he's gonna get hurt".
So he's still mucking around with them, ones on its side, hes 6 foot away, I give it a slight tap on the steel band....
BOOM!! Glass everywhere. He nearly ****z himself. I say "Told you so"
Hes as white as a ghost, can't believe it, says he saw "a shockwave" from the CRT as it exploded, still unsure if I had anything to do with it.
He got glass embedded in his jeans. I start cleaning the glass off the ground & talk about idiots who don't know what they are doing, theres 3 other screens ready to explode just like that one.
The ones he placed there....
He gets on his bike & leaves. Same thing will happen next time he arrives too.
