Exploding watermelons with your mind

•, By Nick Gilbert
 The set-up, created by Chris and Brad from Louisville, Kentucky-based hackerspace LVL1, uses the Star Wars Force Trainer. It's essentially a consumer level electroencephalograph (EEG), which scans your brain waves. When you reach a certain level of concentration, the device triggers an action.

However, in this case, the payoff for your concentration is far greater than with the off-the-shelf Force Trainer. The original Star Wars-inspired device merely caused a fan to turn on and push a ball up through a plastic tower, so as to mimic Jedi-like telekinetic powers.

LVL1's take on the idea, called Mind over Melon, causes watermelons to explode.
Instead of connecting to a fan, this custom rig links the Force Trainer to an air compressor, the signal being handled by Arduino-based electronics. When concentration reaches an acceptable level, the compressor lets off a burst of air, enough to shred said watermelon to pieces.

While this may not be a production-line device for the masses (yet), we like to think it could prove to be the party game of the future.
