I always wanted to go into one of those inflatable rolling balls and roll down a hill. At my age I’d probably throw up after one roll but for kids it’s a ton of fun. The Child Piloted Tumbler lets kids climb into the inflatable honeycomb and roll around like crazy. The 30 chambered globe is made of heavy-duty thick PVC with room inside the 47″ diameter ball for a child up to 100 lbs to move around and shift positions enough to move it with just their body weight. Ten of the chambers are clear so the kid can see where they are going. Just $79 from Hammacher, cheap enough that it would be cool to have a pair (or more!) of these and play some cool games.
