Super Cool Kinetic Sand

Sand is a loose granular material that covers the beaches, riverbeds and deserts of the world. It is made of finely divided rock and mineral particles. Kinetic sand is sand that sticks to itself, so you can form clumps and mold it with your hands. It mimics the physical properties of wet sand. Kinetic sand is a mixture of sand, cornstarch, water, detergent, and food coloring.

Kinetic sand is unusual and super fun because sometimes it acts like a liquid and sometimes it acts like a solid. When you put pressure (or force) on it by poking it or grabbing it into a ball, it acts like a solid and the mixture maintains it shape. But, as soon as you remove the pressure, the mixture loses its shape and starts to flow like a liquid. This happens because when the cornstarch particles are put under pressure they trap the water molecules between them temporality turning the mixture into solid-like material.
