What are examples of adhesives?

capillary action, when you put a tube in water the water will "stick" to the sides of the tube pulling the chain of other molecules with them.

ok no not your mom and dad, but to other molecules... for instance..

the molecular force of attraction in the area of contact between unlike bodies that acts to hold them together.
Adhesion refers to one thing sticking to another. An example of adhesion would be packing tape sticking to the flaps on a cardboard box and holding the box shut.
