De brainwave van de toekomst

You slip the wireless headset on. It looks like something a telemarketer would wear, except the earpieces are actually sensors, and what looks like a microphone is a brain wave detector. You place its tip against your forehead, above your left eyebrow.

A few feet away is a ping-pong ball in a clear tube called the Force Trainer. The idea is to use your thoughts alone, as recognized by the wand on your forehead, to lift the ball. Your brain's electrical activity is translated into a signal understood by a little computer that controls a fan that blows the ball up the tube. Levitates it. As if by magic. It's mind over matter.
