Infinite Water Cup

cults3d

This cup has hollow walls, a hole in the bottom, and a hole at the top. It is meant to be used as a party trick of sorts. 4-inch diameter and 5.5 inches tall. Don't drink out of the cup. Instructions: Pour water into the cup, until the hollow walls are filled. Then pour out the water in the main cup while your thumb is over the top hole. Orient the cup upright and remove your thumb from the hole. The water in the walls should fill up a little bit of the cup. Repeat until the water is gone. V2 might be coming soon to allow more water in the walls.
