The secret, water-absorbing chemical in a diaper is a superabsorbent polymer called sodium polyacrylate. These are the same factors that allow plants to carry water from the roots upwards through vein-like tubes to the leaves. It only takes several seconds to absorb all the water. Soil consists of sand, silt, clay, minerals, water, air and organic material. The small molecules that combine to make up cellulose are sugar molecules; that's the key to the absorbency of paper towels. Create another chart to list the materials that were nonabsorbent. Paper towels and coloured water are great for teaching kids about water absorption. Salt is hygroscopic which means that it can absorb both liquid water and water vapor in the air.
