Liquid in a small brown bottle that used to be sold at head shops for 5 bucks a pop. Now that I think about it the stuff really does smell like crushed ants. A bottle mixed with bong water will make your brain feel like it is in a vice (without the pain). Just make sure to be sitting down prior. Will make ones face turn red accompanied by hot flashes. Too much of it will make car headlights look yellow at night along with a rowdy headache.
