Walmart offers the Uncle Milton Star Wars Jedi Force Levitator for $15.99. (Toys"R"Us and Amazon have it for the same with free in-store pickup and free Prime shipping, respectively.) Opt for in-store pickup to dodge the $5.99 shipping charge. That's the lowest price we could find by $2, although we saw it for a buck less in March. It includes a Jedi training stick and allows your child to levitate the ball with the force.
