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. Best regards, Ron Pickard From: Richard Pittenger [mailto:[email protected]] Sent: Friday, February 19, 2010 2:03 PM To: [email protected] Subject: Re: [PSES] Safety requirements for schools Group, This discussion brings back some old memories for me as well from my Chemistry Class in the early 1960's. 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.
