I would have loved to have a radar gun when I was a kid because little boys are stupid and they like to test their limits. How fast can I ride this bike? How far can I throw this ball? How many cars can I jump on this skateboard?
As far as the speed issue is concerned, kids can now get an accurate measurement from the Mattel Hot Wheels Radar Gun. All you have to do is press the point-and-click handle to get a speed reading from an object either coming towards you are moving away.
The Hot Wheels Radar Gun retails for an affordable $30.
