Guess who built this contraption? You’re right, college students. But as much as we like to make fun, the subject of Beer Pong is our addition, not theirs. The device uses an air stream that can be directed along two axis to control and sort ping-pong balls.
Unlike the lethal ping-pong ball launcher, the goal here is elegant control of the ball. They’ve achieved a great success. Watch the video after the break to see balls sorted into beakers by color, transferred to vessels over a large distance, and navigated through an elevated obstacle course. To give us a hint of what you can do with this, we see the machine controlling an apple, an onion, and a water bottle at the end of the video.
