Abstract
An exercise and/or play hoop, made of semi-rigid plastic tubing, is partially filled with water (30) to between ⅙ and ½ full, most preferably ¼ full. The water improves the dynamics of the hoop and makes keeping the hoop elevated by gyration easier. The hoop is preferably made of a length of hoop tube (10) bent into a circle. A coupling tube (20) is inserted where the ends (11, 12) abut, spanning over the joint. The coupling tube includes a bore (25) through which the liquid flows circumferentially around inside the hoop, and past the joint. To seal the water in O-rings (41, 42) are used. A decorative, preferably iridescent cover (18) may cover the hoop. Tape (50) keeps the joint together. The hoop may be scented.
