This is the super-absorbent polymer found in disposable baby diapers. Also used in many "disappearing water" magic tricks, this fine white powder instantly turns liquid water into a slush-like solid substance. Technically speaking, the polymer absorbs from 500 to 1,000 times its own weight in water. Simply add table salt to reverse the reaction. Safe and amazing -- your students will love it ...

Super Absorbent Polymer Supplier | SOCO Chemical

Super Absorbent Polymer. It is a functional polymer with good water absorption and water holding capacity. Super absorbent polymer’s most beneficial property lies in the fact that it absorbs liquids equivalent to several hundred times of its body mass and transforms it into a gel; That is why it is able to retain or stop the water.
