No genetic tinkering or use of the Force is required, just a hacked up Star Wars Force Trainer (which reads brainwaves, sort of) that controls a CO2 cannon jammed up the wazoo of a watermelon. Concentrate hard enough, and the headset will sense the power of your will and signal the cannon to fire, turning the watermelon (which, for the record, didn’t ever do anything to you) into a tasty pulp.
