If you chew a piece of gum in a smirnoff it will float up and then back down going slowly farther and then get to the top and do the opposite and keep doing it. Weird shit. Late to the party? Probably, but I never fucking drink smirnoff and probably wouldn't throw gum in it if I did.
Maybe it works with other beverages too? I don't fucking know. Just thought it was cool. Hop on the hate train
