Oobleck is a special mixture of powders created to replicate real quicksand. The texture will blow your mind. Simply adding water turns the powder into a goo that can be both a liquid and a solid. Scientists call this type of substance “non-Newtonian” because it doesn’t follow Newton’s laws. Sir Isaac Newton would have been so confused. Due to an exclusive pigment used in our Oobleck, it even glows under black light.
