You’re playing a friendly game of beer pong with your buds and, of course, chase down the little ping pong ball 85 times, dunk it in that sketchy water cup and deem it clean.

It’s a familiar setting and everyone has just accepted that they’re drinking beer that’s filled with dirt, cigarette ash and probably even dog poop residue, but there’s finally a real solution for your dirty balls.

Some geniuses on the east coast invented something that should have been around since the inception of beer pong — protective cups that completely cover your beer.

With the “Slip Cup,” that dirty ball never touches your cheap beer and still keeps the integrity of the game in tact.
