Chemistry and Physics teachers: not sure how I'm still alive
We were playing with light sensors plugged into ZX Spectrums in secondary school physics, and we noticed a subtle waveform in the light output from a bulb. My lab partner thought it was due to the 50Hz mains, whereas I thought that it was flicker from the monitor. We asked the physics teacher about it, and he said:
"Well, you could feed the bulb with 240V DC..."
He helped us connect 20 bench power supplies in series. Turned out it was the bulb.
I also had a pyromaniac chemistry teacher. One lesson we were making a bunch of compounds (really boring stuff, like road paint), and the chemistry guru in my team (he later went on to work as a chemist) suggested that gunpowder was also relevant to what we were studying. They set it off at the end of the lesson... it beat the crap out of the road paint.
