Ever wondered how fast you can pitch? Well you don’t need to buy a radar gun for that, this baseball will do. It has the radar gun built-in so the ball itself measures the speed. With all those gadgets gone in, it weighs slightly more than the standard ball, but then this isn’t for regular play. I’d like to see how fast the ball goes when I hit it with the bat, but that will probably ruin the circuits. Costs $16.98.
