Water Beads Up on Wax Paper

Water forms rounded beads instead of spreading flat. Ask students to predict what will happen. Place drops and push them together/apart. Key idea: Water molecules attract each other more strongly than the waxy surface. Ask: Why is the drop round? Safety and cleanup: Small water volumes only. https://www.google.com/search?q=%22Water+Beads+Up+on+Wax+Paper%22+science+demonstration+experiment
