Why is it that a drop of water spread on a glass surface smeared with wax remains a drop while on a clean surface spreads to form a film?
Wax and water are both adhesive when together, this means that they will stick. Your hands and water act in that manner which is why water feels wet. The water will stick to the wax and won't go anywhere due to its adhesive properties. Clean surfaces and water act together cohesively which is the opposite and means that they don't stick together. This leaves the water flowing freely across the surface with nothing to stick onto.
