A hollow body is provided having two complementary parts releasably joined about interfitting rim portions. When the parts are joined, the hollow body may be compressed to partially deform a portion of the rim structure into an opening thereby allowing the filling of water into the body interior. After deformation the parts resume their original shape. An effective hermetic seal to retain the water within the interior is formed by squeezing the body and purging air through vents in the rim portions. The water-filled body may then be thrown against a stationary object whereby the force of impact will release the seal and allow the water to become suddenly released causing a splashing action. The complementary hollow parts may be subsequently rejoined and refilled with water to repeat the throwing and splashing action.
