Thank you for a clear and well-filmed presentation. Before finding this video, I watched at least five others supposedly explaining how to use a viscosity cup, and yours is the first one that's been worth watching.

All my questions answered. Thanks

Easy to follow instruction, thanks!

Huge help, thanks

thank you

Great video ,easy explanation! Look at that baby face!

higher viscosity means more solute is present. This in turn lowers the vapor pressure of the solution, meaning less of the solvent will be able to evaporate over a given time period. This leads to longer drying times and potentially uneven/excess application.
