Yes there really is a Star Wars Force Trainer, a toy that actually works.
It consists of a headset with about four electric contacts. This communicates remotely with the main unit, out of which protrudes a tube with a plastic ball - sorry, a 'Training Sphere' - inside. Concentrate hard on the ball and the Training Sphere starts to rise up the tube, as you can see here. I found it fairly easy to get the ball moving up the tube, but as soon I started thinking, "Yes, I've done it', it flopped back down again.
Short Sharp Science writes that via Bluetooth and other networking technologies, the headset technology could be a useful aid to the severely disabled.
