document camera or overhead projector and screen (for a medium to large lecture hall), three small watch glasses or a brown paper towel, three dropper bottles with stoppers or lids, one containing water, one containing ethanol, one containing acetone. So that speeds up the process, even though the evaporation from the main surface is slower for the saltwater. Saltwater has another substance dissolved in it (salt), so its particles attach themselves to the water molecules, making them heavier and in need of more energy to escape the surface. As viscosity increases flow velocity decreases. Contact: Randy Sullivan,smrandy@uoregon.edu.
