The "only use part of your brain" thing is a myth. You use 100% of your brain, you just don't use it all at once. This is because your brain's tasks are mitigated by blood flow, & it's just not important enough to waste energy thinking about math constantly when you need to keep breathing.

The other thing is, even if there WAS some "untapped portion" of your brain, it wouldn't allow you to control things with your mind. It requires energy to move objects. Your brain runs on electricity, but the electricity it generates is weak, only vague signals penetrate the skull, which require special equipment (an EEG machine) to pick up. The only forces known to be able to remotely move objects require massive amounts of energies to control.

To put it another way, it's kind of like saying, "You only use a few of your muscles at any one moment, therefore you could fly if you could use them all at once." Actually, you would just be doing some really weird dance.
