The AgSAP™ Water Crystals are nontoxic polyacrylamide granules of super absorbent polymer available from M² Polymer Technologies (www.m2polymer.com). These same water crystals are used to conserve water and nurture plants in arid conditions. They are concealed in the casing of a cotton neck scarf. When the scarf is soaked in water, the crystals absorb the water, expand, and turn into a crystalline gel. The cotton fabric absorbs water from the gel, and then the water slowly evaporates for a cooling effect. Scarves stay cool and moist for hours due to the polymer’s water-retaining properties and the slower evaporation rate than plain water alone.
