The Magic Cup

thingiverse

This enchanting vessel will produce more dramatic effects when printed at 150% or 200%. Once filled to its maximum capacity, it starts to seep water and continues until it reaches half full. At a standard size of 100%, the cup will leak liquor significantly faster than water due to differences in surface tension. Adjust the cup's dimensions to create an impressive R18 party magic trick where only liquor leaks while water remains contained.
