plastic: Aren’t you supposed to hold a sugar cube in a slotted spoon and then drip water over the sugar until it melts?
The French referred to it as the “Green Fairy” for its supposed psychoactive effects (which PadreBrian mentioned).
If you want to really get torched, try some authentic slivovitz or rakia. I had a Croatian friend growing up whose dad used to make homemade rakia (his version used apricots) that ran about 160 proof. Mix it with a little Sprite or 7up and you’re off to the races.
