Malia was able to make a paperclip float on the surface of water. What will most likely happen to the paperclip if a drop o dishwashing detergent is added near it? Soap is a surfactant that increases the intermolecular forces of water allowing the paperclip to continue to float. Soap makes the water less viscous making the paperclip sink. Soap is a surfactant that disrupts the intermolecular forces of water making the paperclip sink. Soap makes the water more viscous allowing the paperclip to continue to float.
