How Many Drops? - Lesson - TeachEngineering When water is dropped carefully onto the surface of a penny, it can pile up into a dome shape before spilling over the small lip around the penny's perimeter. Rubbing alcohol can pile up as well, but spills over before forming a well-rounded dome. Oil will not pile up much at all, as students discover. Associated Activities
