Back when I did cable installs I had a flogger made of RG6. The ends had been very carefully stripped and bent into hooks- that had what looked suspiciously like bit's of flesh stuck to them.
Funny how many customers started listening to what I was saying when that casually got shifted out of the way to grab another tool from the truck.
And here I thought my aviation maintenance teacher was the only pyrotechnic with a teaching licenses.
He decided to end our course on the different types of batteries by retiring a battery that was well past it's end of life period. More specifically he decided to demonstrate the hazards of thermal runaway with a 24 cell NiCad battery... on the backside of airport property... without telling anyone except his boss who lived and worked 3 states away that approved of disposing of the battery in an educational manner.
Apparently his boss wasn't informed of what that educational manner was, that it was going to be done under the flight path of a regional airport, and without advance notice to the Kitty Hawk Airfreight office we were renting our shop space from. He rigged it, ran a couple of LONG cords to it to start the charge process rigged it and ushered us all back behind a plexiglass shield. Nothing happened for about a minute while he explained the internal mechanics, then it started to smoke, then flame, and then hell broke loose and a piece of the sheet metal that housed the cells in a cluster was imbedded in the asphalt a few inches from out protective cover- and the batter had been replaced with a small crater.
If nothing else everyone one left class with a firm conviction to double and triple check every cell in a battery and make sure they were wired properly. If not for others safety, then because we could still hear the college dean chewing out our career center teacher over the phone even when we got to the parking lot.
