Surface Tension experiment - water
Report Copyright Infringement View in OSM UK
Description
Exploring water surface tension using water, tin foil boats and dish soap.
Surface tension allows the cardboard boat to float on top of the water. Adding soap disrupts the arrangement of the water molecules. The water molecules near the detergent are attracted to the detergent as well as to other water molecules, so the surface tension of the water behind the boat decreases.
