SKU: SSS-870225


The magic of hydrogel polymers comes alive when kids put these tiny, colorful orbs into water to soak for several hours. As they grow bigger and bigger, young scientists will learn to appreciate how important hydrogels are for helping the environment in areas where conservation of water is needed. Conduct experiments to see how quickly evaporation occurs in different environments. The tiny orbs take up less space when dry, which is great for storage - but they can be re-hydrated again and again. Plus, the concentrated colors become translucent as the orbs absorb water, which can lead to more science learning. Includes 1.16 oz. of polymer orbs in assorted colors, plus instructions for 3 experiments. For ages 6 and up.
