Science Gone Fun 50 Grams Sodium Polyacrylate Superabsorbent Diaper Polymer

Features

• Sodium polyacrylate, also known as diaper polymer. The size of granular is approx. 0.30mm (300microns), Add water to it. This amazing granular immediately turns into a gel.
• Great use for science classes, holiday gifts, stocking stuffers, party goody bag favors.
• Sensory Bins: Add cups and molds and make sand castle-like creations with the slush (more water).
• Magic Tricks: Make water “disappear.” Put the dried sodium polyacrylate at the bottom of an opaque cup, show it is “empty,” pour water in, then flip the cup upside down. The polymer should absorb the water, expand, and stay inside the cup, making it look like the water disappeared.
• Safe, Not-Toxic. A CPSC-accepted lab tested it in the USA. It complied with the ASTM F963-17 & the CPSIA. See the image for the test report.
