Some Dutch guy just smashed the world record for most basketball dribbles in a minute. It used to be 444, but this guy did 609. Here's what it sounds like when someone dribbles a basketball 10 times per second. (His name is Leon Walraven. The video is kind of mesmerizing . . . for a whole minute the ball never gets more than an inch or so above the ground. It moves so fast that it looks like it's floating.)
