Silly Putty
Description: Silly Putty is a silicone polymer which is a non-Newtonian fluid, similar to slime. It has dilatant properties; it expands when sheared, resulting in an increased viscosity under stress. As a result, silly putty will form thin strands when it is pulled apart slowly, but it will break when pulled apart sharply.
