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 wouldn't be a blast!
This Water Soaked Knee Hockey Rink 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 decide whether the set's sticks are as "soft" as Hammacher Schlemmer claims. $US50.
