Summer may be almost over, but that doesn't mean there isn't still time for fun in the sun. That's especially true when we're talking about running across the surface of the water in a giant inflated hamster ball. Yes, for the low, low price of $275 you, too, can enjoy the lake without actually getting wet. Simply inflate it with an electric pump, hop in, and run around while grabbing at the built-in cups that help you get a grip. Unfortunately, fatties need not apply, as the maximum weight it can support is 170 pounds. Nothing would be more humiliating than slowly sinking into the lake in a big hamster ball, only to be rescued later by the coast guard. Trust me. Hey, don't sweat it, just sit back and keep eating that ice cream; those skinnies don't know what fun is. — Adam Frucci
