POLY means many and MER means unit. Because the units in chains are so long, they interfere with the ability of the solution to flow.
Viscosity is a physical property of liquids that descibes how they flow.
Add 2 or 3 drops of the desired color of food coloring. Take the putty out of the beaker and stretch it. Extensions Try making on of the other non-Newtonian fluids in this lab manual. A non-Newtonian fluid has properties of both a solid and a liquid and reacts to stress with increased viscosity. Towels and water should be on-hand as bits of silly putty will be on countertops.
