In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup. They learn that size can affect the way materials like water behave. They will also get introduced to the concept of surface tension and intermolecular attraction at the macro scale and the nano scale. This is a great activity for a NanoDays celebration, but can be used on its own.
