Can a ball float in the air? Hape makes it so! Place a ball in the base, stack the tubes and turn on the fan - the ball will fly through the tubes til the top!  You can make the ball travel up or down by controlling the air flow. When you put the lid on top, the ball will sink back to the bottom. If there is no activity, the fan will turn off automatically after 5 minutes. Push the orange button to re-activate. This brilliant aerodynamic twist on a classic toy will inspire kids curiosity in aerodynamics and physics. Plus, the rocket design will excite! Featuring animals, shapes and numbers in bright colors, the 7 tubes are also a fun educational tool. Teach your kids about early counting and develop their recognition and fine motor skills.  The novel play-set can be stacked up to over 35'', meaning it suits different ages and heights. Your toddler can sit or stand up to play which promotes balance and coordination.
