Okay, it's not a full range of mage powers. It's not the Force. It's not telekinesis. In fact, it's a fairly limited setup with only one purpose, at the moment.
But it is a chance to make something explode. With your brain.
A group in Kentucky hacked the setup together. It's a Star Wars Force Trainer toy, a device that senses brain activity, hooked up to an air cannon, stuck inside a watermelon. Do enough thinking, and your brain's electricity power's the setup.
So yes, technically, the exploding fruit is caused by the power of your mind. Just don't specify what power that is. Electricity and clever science look dull as compared to incredible cosmic powers.
