Xploderz Water Pellet Guns
It's about time someone offered all the advantages of paintball without the paint. Xploderz Water Pellet Guns ($15-$40) shoot pellets made of a super-absorbent polymer that you "grow" in water before loading into a cartridge and slapping on your weapon of choice: either the pistol-like XBlaster 200, the mid-sized, Uzi-like XStormer 1000, or the sniper-style XRanger 2000. As an added bonus, you can crush the spent ammo into your yard to help it stay healthy in the dry heat — the polymer was designed by the Department of Agriculture, after all. [via]
