How can you make beer pong better? By playing with hexagon beer pong cups designed to fit together.

Hexcup is a redesign of the classic party game. The unique shape of these cups creates a honeycomb pattern when all 22 are positioned together, so they stay put during play. Grooves on the bottom of the cups prevent ghosting—that’s beer pong-speak for when cups shift around. And unlike the traditional red throwaways, these cups are durably built to be used again and again. You can even run them through the dishwasher.

College friends (and engineers) William Heimsoth and Aaron Attebery created Hexcup to make beer pong sessions move more quickly, with less time spent adjusting wayward cups. Their simple but smart upgrade was a hit at a party we went to, as it helped keep the game (and fun) going longer.
