Let's make slime!

This resource explains how to make slime using cornflour to produce something called a non-Newtonian fluid. A non-Newtonian fluid is a substance which has properties of a liquid and a solid. This means it can flow like a liquid, but also can have a set shape. It all depends on the amount of force you apply to it. In this ...
