This is the Star Wars Jedi game that requires you to bring to bear all of your latent telekinetic powers of the Force in order to keep a ball levitating. Similar to EEG technology that reads the alpha and beta waves created by your brain, the game comes with a headset equipped with forehead and ear sensors that translate your brain's energy into a wireless signal that is sent to the game's base station. The station has a tube with a ball inside (resembling the Jedi training remote Luke Skywalker used on the Millennium Falcon) that is kept levitating by a flow of air; your steady concentration adjusts the air fan's speed, causing the ball to rise and fall. One of the most famous Star Wars Jedi characters--Yoda--provides verbal encouragement during your training: "develop your powers of concentration, you will." You can progress from Padawan to Jedi Master through 15 levels of training. Base requires six AA batteries (not included); headset requires three AAA batteries (not included). Ages 8 and up. 16" H x 10" W x 6" D. (1 1/4 lb.)
