We've thrown them out of upstairs windows at work in the past :lol:

I've always said the quality of television's been falling.

Anyway, I had one of those anticlimatic screen breaks once when I droped my PC monitor during a move-in. The crash was folowed by about a half minute of hissing.

BANG !! TV kaput.

If i dismantle old tv's for parts, i usually take the rear cover off and tap the gun with a piece of wood, wsssshhhh!!! The glass at the neck of the tube cracks and the air flows in the tube , so the risk of an implosion is over.
Then strip out what i need and dispose of TV for rubbish.

I shot my bbgun at the back of a monitor. It had a Hissing sound them stopped. The glass was easier to break after works. I found that using a bb gun is the safest way to de pressurize a monitor. I used to use a shovel and hit the back of the glass or the tube till it broke.

Why "Risk of implosion"? The shards should be pulled inside.... Why yould anyone near have any risk of injury? It is not an explosion....

A nitwit in the batch before mine, knocked down the sodium vapour lamp used in spectroscope practicals. The teacher told our batch that the lamp was off... or it would have exploded... All I ever did was put water on a hot incandecent bulb. It cracked.... I do not recollect explosion or implosion.... I did it on a bulb in my bathroom while taking bath....

Because the pieces don't magically 'disappear', they carry on moving so fly back out the opposite side. The implosion from a CRT can throw glass many tens of yards.

So an implosion is very little different from an explosion, in only varies in the actual mechanism in which it works.

Default I have actually done this

In the early 90's, I worked on the special effects for many films, including one called "Videodrome". As a test we shot several different guages of bullets into several working TVs. The results were absolutely unspectacular!. most bullets simply made a nice clean hole, and the picture disappeared, sometimes with a small puff of smoke...most times not. Until we got up to a very large guage, at a very close distance...then glass flew everwhere.
Unfortunatly...just like the myth of spectactular exploding cars in TV and movies, where a car has a huge explosion by merely tapping it with another car, the huge explosion that follows whenever a electronic item is shot, can only be found in fiction.
We decided that it would be far safer, and far more visually stimulating by placing squibs around the edge of the face of the tube, along with several DSC's inside the chassis(Directional Shorting Caps, designed to emit a shower of sparks whenever tiggered...available in spark sizes from 1inch to 60ft).The squibs around the edge of the tube did a really nice job of smashing the tube, and blowing all the glass inward. FAIRLY safe if someone was supposed to be standing near the explosion...and quite visually stimulating!

They did the car thing in mythbusters. They shot at it with what looked like a 50cal at the gas tank. Nothing happened.
