Coelocanth: Not in, but I'll relate my little chemistry story:
Way back when I was a teenager, a buddy of mine and I decided it would be fun to make our own gunpowder. He had all the ingredients at his place, so we proceeded to his basement and started experimenting with different ratios to see what we could come up with (this was long before the internet, so we didn't have access to great info on exact ratios of the ingredients). We did manage to come up with a mix that burned okay, but we weren't satisfied. Anyway, for some reason that I no longer recall, he had a small block of magnesium at his place, so, knowing it would burn, we thought it would be a great idea to mix that in with the home-made gunpowder.
It wasn't.
That shit burns
hot! Luckily, we had sense enough (or the fates decided to be kind to us - probably this is the real explanation) to go outside. We'd loaded our mixture into an old die-cast metal model plane he had and proceeded to light it up with a fuse (just some string as I recall. Something like that, anyway). So we were standing a fair distance away when it went up. It was pretty spectacualar. But the drawback was we'd set the plane on his father's tool box (don't ask me why - I can't recall what the reasoning was). Needless to say, there was very little left of the plane and the tool box didn't fare much better. His father was
not pleased. That ended our home chemistry experiments.
Ahh, magnesium, always good for some pyrotechnic fun. Intentional or otherwise :D
Your story actually reminds me of an incident from back when I was doing military service. We were at a large firing range, one of only a few places in Denmark where we could train with heavy weapons, it having only fields and water in the immediate vicinity. That wasn't why we were there, though. We were there in the dark, and one of the things we were drilling was lighting a battlefield, using a combination of everything from signal guns, over flare rockets, to mortars. As it happens, a lot of those things rely on magnesium which, as you observed, burns hot.
Besides it being night, it was also windy, early summer, a quite warm and dry, but the range master considered the wind no problem since it was blowing -away- from the only town in the vicinity. All good.
As it happens, though, flares launched by a mortar can get up quite high, and last quite a long time. When it is windy, this means they can travel quite a long distance. Such as, for example, into a neighbouring field. A neighbouring, very dry field. Which will promptly catch fire. Leading to a full platoon of soldiers who would really rather be in bed, but were willing to make an exception in this case on account of getting to play with guns and fireworks, instead being pressed into service as firefighters.
It took us a good hour to put out all the fires we'd inadvertedly started. But at least we managed to light up the battlefield.
