My prince of darkness physics teacher
When I was at school I had a physics teacher who was great if you were on his good side but a complete sadist if you crossed him. He would tell his a-level class his tales of revenge when he was in a good mood.

1. When he was at university his class had to build electrical circuits and test how they reacted to a powerful magnetic field. The magnet in question was a large electromagnet with two poles facing each other, securely fastened. The circuit board would go between the poles for testing and the magnet would be switched on. This teacher used to loosen the fixing on one of the poles so when the magnet was turned on, the poles would slam together, instantly destroying the circuit in between them.

2. He used to work for siemens, manufacturing microchips in the 80s. To get the day off all he had to do was tear up a piece of tissue paper in the static-free, dust-free manufacturing floor. The tissue particles would take the whole day to clear and would ruin that day's production.

3. He used to make spoons out of a metal alloy (I can't remember the name) that would melt at about 60C. He would leave these in the staff room and the teachers would become all confused when their spoons melted.
