Creepy ether
Long ago, I poured a litre of diethyl ether onto a soon to be bonfire. I wanted to see how well ether 'crept' (in the words of various chemistry teachers). I approached with a very long stick, with a flaming brand at the end, until it met the vapour front. It didn't explode, but the garden around the bonfire was instantly transformed into a pool of fire. The bonfire caught nicely too!
Unlike the firemen, I was expecting the outcome. However, if I did it again, I'd probably wear some eye and ear protection.
