Re: F*&^ knows what they'd have done with my chemistry teacher
"alkanes involved an overzealous sampling of methane from a gas tap next to a lit spill creating a jet of flame across the lab, toluene and a nitrating mix with insufficient cooling resulted in a rather careful but rapid exit for the class".
Oh dear - this does take me back....
What was the trick of introducing an airlock into a bunsen that would eventually extinguish someone else's flame?
An experiment with ether in a beaker. The vapour gradually crept invisibly across the bench until it reached a neighbour's lit bunsen - just like a fuse trail.
Heating toluene - caught fire and large oily black particles drifted over every surface in the lab.
One lad spilled a beaker of an acidic reaction on his smart nylon lab coat which just morphed into a white plastic mess. Old fashioned cotton ones were much safer.
Several times chemistry teachers stood in front of their desk to lecture the class. Then a smell of burning announced a large brown streak up the back of their jacket from the always lit bunsen on their bench.
The VIth Form making chromium dichromate - the final step was allowing the excess water to slowly evaporate over several days. Just when it was expected to be dry the beaker was mysteriously filled with water. Apparently the senior Chemistry master had lost his nerve over what can spontaneously happen when it gets very dry.
The VIth Form trying to making nylon by passing nitrogen over something (amide?) heated in a tube. A lad's father worked for BOC and had arranged for a large cylinder of nitrogen to be delivered. A piece of rope round a tall tap kept it upright against the bench. As the experiment started a foul gas came out of the rubber tube attached to the end of the apparatus. Quick thinking stuffed the tube end down the sink waste hole - problem solved. This was in the small prep room - the next thing was a class being evacuated from the main lab as the fumes re-emerged from all their sinks. It never did produce any nylon though - only the "nylon rope trick" did that.
