Smart Fluid

Based on a foodstuff ingredient, this is the perfect non-toxic material for demonstrating and exploiting the remarkable property of shear thickening. When the powder is mixed with water, it forms a creamy white liquid that thickens if rapidly disturbed by stirring. It can change from fluid to almost solid and back again in a split second and provides a breath-taking demonstration of rheopectic behaviour - the opposite of thixotropic. Supplied in water soluble powder form: 500g bag.
