vis·cos·i·ty
ˌviˈskäsədē/Submit
noun
the state of being thick, sticky, and semifluid in consistency, due to internal friction.
synonyms: thickness, gooeyness, viscidity; More a quantity expressing the magnitude of internal friction, as measured by the force per unit area resisting a flow in which parallel layers unit distance apart have unit speed relative to one another.
plural noun: viscosities
Viscosity can be defined as the measurement of a liquid's resistance to flow. Consider water and molasses. Water flows relatively freely, while molasses is less fluid. Because molasses is more resistant to flow, it has a higher viscosity than water.
There are several ways to measure viscosity. One is to fill a bowl with a hole in it. The time for the fluid to drain indicates the viscosity.
A second way is to drop a ball into the fluid and time its fall.
Here is an explanation with pictures of the second method:
