A light twig is barely floating on the surface of water. What will most likely happen to the twig if a drop of dishwashing detergent is added near it?

It will sink below the surface. Since dish soap is a surfactant, it will alter the water's surface tension. Lowering the surface tension, the water will no longer be able to support the mass of the twig.
