If you mix corn starch and water in the right proportion, it acts really weird. You can easily run across the surface if you keep moving fast. If you slow down too much though, you'll sink. The mixture is considered a non-Newtonian fluid, which means that it does not follow Newton's law of viscosity, i.e. constant viscosity independent of stress. In this case, putting the mixture under high stress makes it more viscous.
