Expandable water toy

[2] Expandable water toys are also sold in the shapes of other things, such as dinosaurs, sharks, people or mechas from popular anime.

The development of superabsorbent technology and performance has been largely led by demands in the disposable hygiene segment.

[3][6] A 2012 paper documented the case of an infant who had swallowed a 1 centimetre (0.39 in) "Water Balz" product, which grew to "the size of a golf ball" in her digestive tract, requiring surgery to remove it.

[3][7] Orbeez states that their product expands to only 7 millimetres (0.28 in) in the intestines if swallowed[2] and will pass through the digestive tract,[8] but that it is a choking hazard and is unsuitable for children under five.

Ireland, Poland, Cyprus, Lithuania, Hungary and the United Kingdom have recalled the Magic Grow Reptile and Dinosaur Eggs Wild World due to a choking risk.
