Since most people—especially drunken ones—don't have expert aim in a game of beer pong, there's The Clean Cup to save you the trouble of having to clean off ping pong balls. After rolling under dusty cabinets, picking up grit off of floors and mingling where feet have been stepping, The Clean Cup is like a car wash, but just for beer pong balls.
The automated, portable ping pong washer uses high pressure to thoroughly wash ping pong balls in about five seconds, so that there's hardly an interruption to gameplay. To be sure that your ball is clean, the device even has an indicator light. This might not seem like a necessity, but during The Clean Cup's Kickstarter campaign earlier this year, there were some eager people to make a pledge in order to scoop up a prototype.
