Amongst everything else, there is a small bit of common knowledge that curious children and science students share.
This knowledge is about a strange substance that fights back when force is applied to it, but flows like water when left untouched. The science students may identify it as a Non-Newtonian fluid, but the children have a much more interesting name for it – Oobleck!
Oobleck, although given a rather abnormal name, is made up of extremely normal ingredients. When corn starch is combined with water at the right proportions, it creates a thick, milky-white fluid.
