my old teachers
My physics teacher, Mr Mcharry, pretended to be very strict, performed fantastic heath-robinsonesque experiments, that took up the entire classroom.
Attempted to demonstrate perpetual motion by using a cylinder vacuum cleaner with a 15 foot hose on each end, one had a funnel in.
The idea was to pour table tennis balls into the funnel, fire them out of the other hose and back into the funnel (some poor "volunteer" got to hold the firing end of the hose). Of course the balls went everywhere except into the funnel.
He also used dry ice for experiments, he got this by wrapping the nozzle of a Co2 fire extinguisher in a towel and letting it off.
He then picked the frozen Co2 up with his fingers. If it wasn't for him I would never have passed physics.

An alcoholic but extremely gifted art teacher.

After going co-ed, they needed a female PE teacher, who was young and very fit, used to walk very slowly past the boys and always wore very tight fitting tracksuits.

There are plenty more examples from that school but listing them all would take far too long.
