Jun 14, 2011 · Make Water A Gel. This demo uses sodium polyacrylate, a super absorbing polymer found in diapers, to turn water into a gel. The sodium polyacrylate has carboxylate anion portions and sodium cation portions.
Sep 28, 2017 · Super-absorbent polymers, such as sodium poly (acrylate), were first developed in the late 1960s by the US Department of Agriculture. They were searching for ways to hold moisture in the soil more effectively. Early attempts were based on starch – a naturally-occurring polymer made from glucose molecules strung into long chains, which swells ...

How is the fake snow powder like slush powder? How is it different?Is this a chemical or a physical change?What kind of uses are there for this kind of polymer?Note:Be prepared for a mess and have cleaning supplies available. 1. Follow the package instructions for the appropriate proportions of snow powder and water. A tablespoon or two of powder will nicely overflow a 250 mL beaker. 2. Measure instant snow powder into a large beaker, a cup, a bowl or a volunteer’s hands. 3. Slowly pour water onto the sno...
Start with coloured water and make colourful snow. Spread the ‘’snow’’ into a thin layer and let it dry. You can repeat the experiment over and over.
Hello, thanks for watching. In this video I will demonstrate two cool things to do with sodium polyacrylate along with a hopefully easy to folly explanation....
