An Inflatable Car to Play Mario Kart Wii In
Crafted by CTA, makers of a large number of electronics accessories, the car is basically an inflatable seat, with a sturdy steering wheel with room for a Wiimote to slot into it. The car inflates in minutes, can support up to 300 pounds, and is going for $40 on Amazon.com.
Yup. 40 bucks to get the next best thing since the car bed.
Warning: We understand that the urge to play Mario Kart from a pool will be strong. I imagine that the urge to bank around turns will also be strong. Do not combine the two.
