A friend of mine did something similar when we gave him a flaming shot that he was supposed to drop into a 1/2 mug of beer (and PUT THE FLAME OUT BEFORE DRINKING..). But he was a little too far gone already and was really fascinated by the flaming glass, which he picked up and looked at really closely. He was even more fascinated when the 151 on top of the shot sloshed over onto his hand & down his arm and the flame followed. At least he had the sense to not drink it at that point.
