Haha, I did that when we worked in the hospital kitchen in high school. Gave it to this guy and said "here, smell this" and he took a huge whiff and was out for a couple days. Dumb a*s.
Then we made more and froze it into ice cubes in the 20 below freezer, and put it in the air vents in the cafeteria. It melted and blew the vapors in, so they had to evacuate because of the fumes and we didn't have to work that day, but when they investigated it was all evaporated and they never figured out where it came from. I can't imagine what sort of an idiot would do that - teenagers don't think like normal people
