My son bought an Air Hogs Zero Gravity Real Rides Remote Control Wall Climbing car with his Christmas money. It’s a neat idea, but how does it work? Great on the ceiling, but not so good on the wall, and terrible on the floor. But you don’t buy something like this to drive on the floor. Watch the video, and you can decide if it’s worth buying or not. Air Hogs makes a lot of other neat tiny remote-control cars, helicopters and motorcycles.
