What do you get when you combine ultra-fine sand and the key ingredient in Silly Putty? Kinetic Sand, and this 'non-Newtonian fluid' has got some bizarre properties.
Very good for showing properties of different types of materials like silly putty. If you make it into a sausage and pull the ends quickly it snaps like glass. Pull it slowly it stretches like a soft dough. In between this it shows properties like a normal malleable metal such as copper, it stats to stretch then snaps. Throw it at a wall and it bounces. Leave it sitting it slowly creeps into a pancake.
