It costs $4,500, it's easy to set up, and it lets you live out your American Gladiators-induced dreams of riding around inside a giant ball, wreaking havoc on your surroundings. It's called the Human Bowling Ball, and it's basically a giant, inflatable bowling game that lets you (the ball) knock down oversize pins inside a makeshift alley. Here's the official product description from Hammacher Schlemmer:
For ages 5-12, the transparent PVC ball is inflated to its full 7' diameter by an adult with the included blower—a zipper cinches the ball closed yet opens quickly to allow egress and quick entry for another player. A player simply runs forward inside the ball, generating momentum to knock over six 5'-tall foam pins that yield easily at the point of collision. An included stationary air blower keeps the 3'-high lane boundary constantly inflated to an optimal firmness to keep careening bowlers within the lane's confines.
OK, but when bowlers start careening outside the lane's confines is when things finally get interesting. And what is this "ages 5-12" bullshit? Did Atlasphere teach us nothing? Besides, if you're a parent that's going to shell out $4,500 on this, you're definitely going to try it yourself.
