http://www.geospaceplay.com/air-kicks-active-toys/bouncearoo-hopper-ball/ You've seen smaller versions of these perennial backyard favorites, but never one THIS size! The GIGANTIC size of the BOUNCEaROO™ compels kids (and even adults!) to climb on and start bouncing.There's something irresistible, almost addictive, about playing on a Hopping Ball. Kids and adults use their leg muscles to launch into ever higher orbits, the energy transmitted by the ball elevating them ever upward, landing in a new spot every time. If parents can ever pry them off, kids end up exercised, soothed, and alert. What more could a parent ask of a toy? Made of durable, heavy-gauge vinyl, it includes a separate foot pump that lets everyone get right to bouncing!For Ages 5 & Up. From Geospace International
