How to (almost) kill an OFSTED inspector
Not entirely on purpose mind...
Going back a few years, A-level physics. Me and a mate conducting a "lift" experiment whereby we calculated the lift generated by a propellor by the negative weight it generated at differing rpms. Unsure how it all worked now, but we were dead chuffed and our physics teacher was dead proud of us. Until one day...
Due to the fact that the prop motor we used was unrated, we had to think of a way of knowing the rpm of the prop another way - and we found an old strobe light, the theory being that if the strobe flickered at the same rate as the prop span, the prop would appear "still" (which it did - cue much hilarity when forgetting if the motor was on or not).
So there we are, darkened room, prop spinning, strobe light flashing. We hear a voice outside our cramped dark room saying "and in here we have two of our most promising students". Door opens, teacher sticks head in, followed by OFSTED inspector. Who was, previously unbeknownst to us or any of the school staff, epileptic.
