What do water, juice, and milk have in common? They’re all liquids which means they will take the shape of any container they’re poured into. It also means they will lose the shape of a container and spill everywhere if they’re poured out. And we all know cleaning up a mess is no fun. But you know what is fun? Kinetic Sand. Just like a liquid, you can put it in a container and it will take on that shape. But why does it keep the shape and not spill everywhere when you pour it out? It’s because Kinetic Sand is a Non-Newtonian Fluid, which means it acts like a liquid and a solid.
