'''Viscosity''' is a liquid's resistance to flow. [http://antoine.frostburg.edu/cgi-bin/senese/searchglossary.cgi?query=viscosity&shtml=%2Fchem%2Fsenese%2F101%2Fglossary.shtml] Honey has a high viscosity; a Wendy's [[Frosty]] has such a high viscosity it's sold with a spoon and a straw (unlike [[Mountain Dew]], which comes only with a straw).

*It describes the internal friction of a moving fluid. A fluidwith large viscosity resists motion because its molecular makeup gives it a lot of internal friction. A fluid with low viscosity flows easily because its molecular makeup results in very little friction when it is in motion. <ref> [http://www.princeton.edu/~gasdyn/Research/T-C_Research_Folder/Viscosity_def.html (Princeton University)] </ref>
