BTW, as far as the old CRTs, a lot of people were "incidentally" taught by those things. They were nothing but bombs. There was a standing joke that if you work on one you had to be a bomb specialist. Red, blue or green. Don't cross the wrong wire. LOL

I am sure a lot of people here in the forum have seen one explode in their lifetime when acted upon by an outside force. I guess it is only fitting that they are used in a lot of "tv" shows and movies as homemade bombs. Can we say MacGyver.

I remember stories of Mac techs from the 80's - the whole case of the original Macs was so small, that before you did any other work on a MAC which required you to crack the case, you had to release the charge on the CRT flyback transformer.

In every Mac repair kit was a degaussing rod with a grounding cable, called by every tech I spoke with the "Divining Rod". Never having done one myself, the one repair manual I was shown warned that the force given from grounding the flyback would forcibly throw the rod backward - possibly injuring the tech's arm. My one friend showed me a technique of striking the transformer with what looked to be considerable force, but the energy release cause the rod to stop in mid air before damaging the transformer - he called learning the exact force necessary to be an acquired art.

Probably the reason why you touch a potentially live (though low-voltage!) circuit with the back of your hand. So that if your muscles jerk, it won't be to close your hand!

Not exactly the same situation, but in our HQ we had a routine electricity safety check, that discovered that about half of our 100 new electricity leads were wired back to front.
Not important with AC you say? Unfortunately some appliances only have an off switch on the active wire. Thus in some cases there would still be power going in, just no return connection. That connection could be made via the earth and your hand.

Probably the most iconic scene featuring a monitor to fashion a bomb is in Die Hard when Bruce Willis used a blasting cap and a monitor and tied it all to the back of a chair - to direct the blast downward - then threw it down the elevator shaft just to get an officer's attention.

"BADA BOOM. BIG BOOM!" Leeloo, from Fifth Element. Also a Bruce Willis movie.
