Diaper Polymer Drinks Water

Tiny powder traps a large volume of water into gel. Ask students to predict what will happen. Add water to small polymer sample. Key idea: Charged polymer chains attract and hold water. Ask: How can a little powder hold so much water? Safety and cleanup: Avoid inhaling powder; no ingestion. https://www.google.com/search?q=%22Diaper+Polymer+Drinks+Water%22+science+demonstration+experiment
