Most "wrong" fun in the lab/shop/biz/bench? Keep it clean!

TV repair shop: We had a game we called "One Twenty to the Board." (USA, and are mains power is typically 120V) We would take junk PCB's and attach a stripped AC power cable to two random spots and plug it in. Sometimes nothing, sometimes MASSIVE showers of sparks. More than a few times we would blow the 20amp breaker which was actually next door!
We found that the large 40-ish pin chips were the best... they'd look like Roman Candles going off. Tons of fun.

Year circa 1960
At Radio Row lower Manhattan NYC
TAB surplus, 111 Liberty St. Old warehouse, with war surplus store and power supply mfg
My first Summer job: I was just the kid, a go-fer.
I learned a LOT that Summer....
When closing up, with breakers OFF a tech placed 1 W 10 Ohm carbon comp resistors inserted carefully into the mains outlets.....various places like behind sales counters and mamagement offices.....
Next morning the boss (who usually opened up) got a BIG SURPRISE as breakers were turned ON.
BANG! SMOKE! FLAME! at each rigged outlet.....

I have a 300V power supply, sometimes I would put 1k ~ 22k ohm 1/4W resistors across it and watch the fireworks.

When I was an apprentice mechanic, one of the guys quietly wired the cars ignition coil to the drivers seat and asked me to drive it it… sure enough, I turn the key and feel like I’ve been shot in the butt :-DD
I still drove the bloody thing into the shop with it zapping me the whole time though :-DD
You probably couldn’t get away with that these days but was all in good fun :) Good times :)

Early Weller TCP soldering stations had a transformer base on the front with 24V AC terminal posts to connect the iron. A small bead tantalum discreetly wired across the terminals never disappointed :)
