Rein in speedsters when young

Hot Wheels are most famous for their collection of toy cars, so what better way to teach youngsters about speed than with the Hot Wheels Radar Gun? This device enables tiny tots to act as traffic police, reading the speed of their toy cars as they speed along the track. Of course, you can’t use this point-and-read device with all Hot Wheels vehicles since some of them are not compatible. Powered by a quartet of AAA batteries, you will be able to pick up the Hot Wheels Radar Gun for $29.74 at Walmart.
