This Shitty Prank

This prank may look sick and disgusting, but this is a 'must try' prank if you are a prankster. The instructions are shown in the picture. Fortunately, this is odorless (you can add experiment with colors or fragrances if you want!). This is one of the nastiest pranks you can think of. Imagine the expressions on people's faces who get to see this artificial shit!
