This seems like a very creative way to both spill all your beer and ruin your Roomba. Personally I find beer pong kinda gross. That ball is not clean, I don't care if you dip it in water or not. You're really just playing an elaborate game of "I hope I don't get diarrhea from this".
I'd rather just play Bounce Off while drinking a fifth of bourbon. That's how classy people roll.
