--- Quote from: Gyro on July 29, 2020, 07:52:27 pm ---Ah, the youth of today. :) It was a small plastic (or sometimes aluminium) cylindrical container with a sealed tight fitting plastic lid - used for storing and protecting 35mm still photographic film canisters when new, and after exposure. Easy to flip up from the edge but it takes a surprisingly large amount of internal pressure to pop it off. --- End quote --- Heh. If you want a bit more old skool - a magnesium flash bulb across the power rails >:D Admittedly that's a bit before my time though so no idea if anyone really used to try that, it was "what we used to do" conversations from the older guys. |

Yep did the roll a chair over bubble wrap before, but luckily during just working at a PC. The sound it makes is spot on to the horrible noise of catastrophically failing power electronics, the only thing missing are the flying sparks and bunt smell. But in terms of pranks we used power resistors instead. Put one of those across a lab supply to get it nice and toasty and then just hand it to someone while you hold it by one of the pins (Just don't make it hot enough to actually cause a serious burn). |

Another old trick is to roll a turn or so of solder off the reel, cut the length in half & insert a piece of tinned copper wire (TCW), soldering it to the solder (it sounds a bit difficult, but it really isn't.) Roll the "doctored" length back on, & leave the roll where someone is likely to be doing a lot of solder joints. They won't notice the TCW until they try to heat the end & the heat runs straight up the copper to their fingers! |

I used to tell the junior engineers who enjoyed popping bubble wrap between their fingers that mental institutions used this exercise as therapy for their patients. |
