We all know how glue or tape can be used to stick two objects together. These adhesives cause the two objects to cohere (or adhere) together. Cohesion is the word for this sticking force. Cohesion also occurs on common everyday objects – rain to a car’s windows, dust to the ceiling fan, chewing gum on Mom’s carpet. This experiment demonstrates cohesion in an interesting situation – and Mom’s carpet stays looking as good as new!
