as a high-performance action sports water ball. Most waterballs are sold in sporting goods, toy stores, outdoor stores and even food stores. The WaterRipper was launched in the United States in July 2010. The Waboba ball was initially marketed overseas, introduced in Scandinavia 2005 and in the United Kingdom in 2008. It is now sold worldwide. Size, shape and materials The high-performance waterball is generally the size of a golf ball or stress ball designed for catching with a single hand. Different waterballs are made of different materials. Most high-performance waterballs are sealed balls and are made out of different types of rubber or neoprene with gel material center and polyurethane and Lycra jacket. The new generation waterball is water absorbing with fluid high-density particulate contents. There are patent pending designs for "high density" or "balanced density " materials in making the new generation waterballs. High-performance waterballs come in different sizes and shapes. There are a handful of high-performance waterballs such as Waboba Ball, Water Bouncer, and the WaterRipper currently sold in the US. The sealed or water-absorbing, high-performance waterballs are typically or larger and made of soft rubber generally with a neoprene single seam jacket. These balls are designed to bounce on the water surface. The water absorbing waterball is the smallest of these high-performance waterballs. It is a collapsing bag or sack like a footbag with an Ultra Suede single seam cover and beaded fill with other water absorbing high-density materials. It is designed to skip and roll on water in a low profile skip pattern. It is less than in diameter and it easily fits and collapses in a small child's hand. It looks and feels like a footbag or Hacky Sack. The water absorbing waterball like the Waboba Blast Ball and Water Ripper Ball are the only high-performance waterballs designed to absorb water. Sealed waterballs vs. absorbent waterballs There are actually two types of high-performance waterballs. While all waterballs float on water, there are some that absorb water and others that are sealed. Sealed waterballs generally bounce higher because they simply repel & displace water. This type of waterball requires the players to have a grip or "timed grab" to catch the ball in flight and stop it. Because they bounce, they are generally hard to catch and often require two hands or a mitt or glove to control or catch them and more suited for
