Nowadays the kids practice dividing up other restricted substances on a mirror with a razorblade.

Yes, it's all very sad. For an interesting thread on this subject started by one bright youngster see
Ok nostalgia time.. I remember chatting to the science teacher and idly nudging the balls of mercury together that were kicking about his desk. He went ape-shit shouting the odds as to the dangers of handling liquid mercury, no mention of his responsibility for having it laid about where children could handle it. Ahh! the best days of your life eh.
MNT or DNT possibly, but not TNT.
Maybe -- I don't now recall enough of the details of what we did. It was certainly exposive though...
Not sure you would want a tilt switch on a car bomb, most use timers.

I thought TNT being a high explosive required percussive ignition. According to my grandfather, who was an industrial chemist, it's quite stable stuff otherwise.
We did the TNT synthesis too, and I'm sure it was tri-, not mono- or dinitrotoluene (at least that was what "chalky" our teacher claimed we were making, and the reaction theory backed it up). It could be that his intention was to terrify us, and if so he was successful as we all were very wary after being told to be careful not shake it in case it exploded.

I wonder if teachers still have nicknames that last for generations.
I guess that "chalky" was because his name was "White"?
I had a number of teachers who had been at the school that I went to and its predecessor for most of their working lives and I have elderly relatives who were taught by them and knew them by the same nicknames, so the names had stuck for a good 30-40 years.

That was so Hans Blix wouldn't see them pushing it about in wheelbarrows.

Many thanks to each and all for the responses. I had no idea that my little message would provoke such an interesting thread. It recalled some of my own experiences in chem labs at school and later in life. I'm still looking for a small qty of mercury though.
Thanks

Hi,
How small and what for? One or a few mercury tilt switches might have enough, or try:
cheers, Pete.
Thanks Pete,
Also thanks for the google link, I'm fairly sure that I have already looked at most if not all of them. I'm not sure of the quantity but prolly about
150-200 grams (it is now quite late in the day and I could be miles out). As my op said this is for refilling a mercury barometer, perhaps several. I'm quite sure this stuff does exist in the wild. The idea of buying tilt switches and wrecking them for the contents doesn't really do it for me but thanks for the suggestion.Sunbeam
