High school was great fun. I had a physics teacher who would last about 10 seconds in today's environment, but we had a ball and learned stuff at the same time. His home made cannon (length of pipe with a spark plug welded in one end, add natural gas from the spigot on his desk, stuff cork in end, hit spark plug with a 15 kV neon light transformer "to insure ignition") was always fun. Nobody slept through that one. Blew a hole in the ceiling the first time he fired it. Tethered the cork from then on. And the Van de Graff generator hooked up to the door knob of the class room. One cold winter day I got to class and got zapped when I tried to open the door. OK, cold dry day, I built up a charge coming down the hall. Reached for the door a second time and got hit again. Once is me, twice is PETE!. We grabbed it again and opened the door, knocking over the equipment. And the teacher? Sitting at his desk laughing! Or, he'd have 2 kg weights swinging through the door! way on long lines from the ceiling. Figure out pendulum motion or else!
Ah, my senior year of high school was great fun. Kids today don't know what they're missing. Ghery S. Pettit From: [email protected] [mailto:[email protected]] On Behalf Of Pickard, Ron Sent: Friday, February 19, 2010 1:32 PM To: [email protected] Subject: RE: [PSES] Safety requirements for schools Ah yes, high school chemistry also back in the early 60s. That takes me back as well from trying to put out ignited magnesium or phosphorous (nothing worked in the lab, we had to let them burn themselves out) to seeing what happened when a chunk of sodium about the size of a fist was put into water. The approx. 8ft dia. burn spot on the ceiling was a very exciting result. Another result was not having those experiments performed after that. Anyway, it's getting late on a Friday afternoon, so have a good weekend to all.

One day, the teacher took a beaker of gasoline and lit a match. He then proceeded to extinguish the match by dunking it in the gasoline. All of us students thought we dead, but as it turned out, the match was 'safely' extinguished as if it had been dunked in water. I doubt if this experiment is still used today. Good day, Richard I.

It was our chemistry master who went one better while producing hydrogen in a large semi john. He lit the end of tube before allowing all the air to purge. Big flash and explosion, glass and acid everywhere, but amazingly in a class of 30 kids there were no injuries. No inquiry or follow up either but then this was the 60's.
