Radio controlled toy cars have always been fun to play with, even back when I was a kid, but you need to find a big open area where you can drive without running into stuff. Now with these gravity defying Air Hogs Micro R/C cars, you can actually drive right on any flat wall, or even up on the ceiling. A powerful fan built into the top of the car creates a venturi effect between the bottom of the car and the wall, effectively sucking it onto the surface. Just keep your fingers crossed that the batteries don't happen die at an inopportune moment.

The Air Hogs Zero Gravity Micro R/C cars are available now for about $44 each.
