Cook up fake vomit
SpacePaintings' recipe for vomit is ingenious. The ingredients seem random: a kitchen sponge, Elmer's glue and of course-- food coloring.
Similar to the fake eyeball gush video, this is a necessary item in any prankster's back pocket. Best yet, it's reusable.
It's a tutorial that spans two of our favorite categories: food and pranks. A perfect hybrid.
