2C60.40 - Silly Putty
Set the silly putty on a very solid surface. HIT THE PUTTY VIOLENTLY WITH THE HAMMER!!! Due to the fact that silly putty has a lower viscosity for slow shear rates and a high viscosity for fast shear rates the putty will shatter like a large crystal.
Another product that acts much the same way as silly putty is called mung. This is made by mixing corn starch and water to the desired solid/fluid consistency. Again this has a high viscosity for fast shear rates.
