Instant Solid Powder

This super-absorbent polymer does tons of amazing things! It can absorb 200-300 times its weight in tap water and hold it in a gooey gel! This powder is also known as slush powder, as it instantly turns a liquid into a solid. With certain ratios of powder and water, the gel becomes a solid! This Jumbo Test Tube comes complete with Instant Solid Powder, three food-coloring tablets, and lots of fun experiment and project ideas. $7.99
