'Helping' the Uni Lecturer ...You'd think by the time they get to teach at Uni they'd know better. We were doing transducers, so he had a compass with a couple of turns of wire wrapped around it to demonstrate magnetic fields.
Out comes his trusty AA battery to demonstrate turning the indicator first one way, then the other. Thing is, he must have been using this self same battery since he was first shown this demo for his 'O' level physics. It was flatter than Norfolk!
"No probs!" says a keen Dio, who promtly offers up a mobile phone battery. Being conscientious type I started to speak: "You might want to be a bit careful, tho 'cos that's a NiCad cell and can dump quite a few ... " ****YEOUCH! FUCK! FUCK! OUCH!**** "... amps in one go if you short it out."
Yes, he had just re-invented the electric heater IN HIS HAND. Melted plastic insulation clung to the pads of his fingers and the lecture took an early coffee break while he went to run them under the cold tap for a while. I claimed the experiment as a Dawin Success.
