Product features Material(s): paper, plastic Colours: white, red Product description Play beer pong for Halloween with this set of 24 cups with a blood-stained print and 12 "eye" balls. The rules are simple: place the cups in a pyramid shape on each side of the table and fill them. Each team stands at each end of the table. Taking turns, you can throw a ball; if it lands in one of the cups, the opposing team must drink it and then remove the cup. The winning team is the one that makes its opponents drink all the cups.
