Hello, Just to add to this, corn starch is a great example of viscous material, if you mix it with water and then stir it, it is very difficult to stir fast because of the high resistance. However, if you stir very slowly, then the resistance becomes much smaller. You can think of viscoelasticity as a spring plus a "corn-starch" like behavior. 

Thank you
