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.
