The H2FO is a disc-shaped toy designed to LOOK like a flying saucer but to SKIP across the water surface to play catch and for creating trick or unique skips.  Another use: watch the H2FO dart back and forth like a flying saucer as it floats to the surface after it is placed flat to the pool bottom and released.  Each H2FO AquaSaucer is approximately 7.5" in diameter and made of flexible foam.  The standard-handed mixed colors are Red, Orange, Lime Green, and Light Blue.
