Hockey is probably not the safest of sports to play while sliding around a water-soaked mat on your knees, wearing nothing but a skimpy bathing suit for protection. But that doesn't mean it might be a blast to try it that way!
The Water Soaked Knee Hockey Rink pictured above is lined with 30 tiny nozzles to spritz you while you whack around an oversized plastic puck with a buddy. Hook it up to your garden hose and brace yourself—it'll be up to you to discover whether the set's sticks are as "soft" as Hammacher Schlemmer claims. $50. [Hammacher Schlemmer via Incredible Things]
