Ok, so you have a small (steel) sphere placed into a graduated cylinder filled w/ 100% pure of a liquid: water, and another w/ glycerol. What is happening on the molecular level that makes the glycerol "more viscous" than water? Is it the nature of the intermolecular forces? IF so, explain.

Viscosity is defined as that property of any fluid (liquid or gas) that tends to resist a shearing force. All fluid motion is accompanied by shearing forces. There are two basic viscosity parameters which are dynamic and kinematic viscosities.
I'm sure that the shearing forces developed are dependent on the nature of intermolecular forces as you stated, within the fluids and between the fluids and the walls of the fluid containers, but I don't know of any sources that discuss the subject, since the viscosity values are all measured and determined with mechanical systems and devices that do not require any further scientific explanation.
