The Jedi make great use of the Force to amass knowledge of the galaxy, and they store all that knowledge in their Jedi Holocrons. This Star Wars Science Jedi Holocron is the pinnacle of their success of knowledge gathering! (Okay, so maybe it's really just a cute game, but that's even better)! It will make you believe that it knows exactly what you're thinking in 20 questions or less. It's a fun toy for Star Wars fans or young Padawans in training. - Holocron is a 3" cube with LCD screen and push-buttons on one side - Uses an algorithm to deduce what you're thinking by asking questions - Answer the questions by pressing the appropriate button - Requires 2 AAA batteries, not included
