Put simply, walking on non-Newtonian fluid (cornstarch + water) could quite possibly be the next best thing to walking on water. Video after the jump.
When the suspension nears the critical concentration – becoming like single cream in consistency – the so called “shear thickening” property of this non-Newtonian fluid becomes apparent. The application of force – for example by stabbing the surface with a finger, or rapidly inverting the container holding it – leads to the fluid behaving like a solid rather than a liquid. More gentle treatment, such as slowly inserting a spoon, will leave it in its liquid state
