Mixed toluene with hydrogen peroxide.
It did not fizz. It did not bang.
Well, poo; I was looking forward for a bit of sparks *sigh*
My prof was as excited about this attempt at explosion as I was and had glitters in his teeny moleman eyes, as he babbled about what not to mix with hydrogen peroxide (which included what the germans used for their V2s) but no such luck happened as to give us the entertainment we wished to unleash upon ourselves.
Apparently, Prof has been mixing and fiddling with chemicals since he was a kid. Suppose all geeks start like that but it's only those who survive the explosions get to university to make great people of themselves. Survival of the luckiest, I guess.
