"Back in the 1700s, Isaac Newton identified the properties of an ideal liquid. Water and other liquids that have the properties that Newton identifies are call Newtonian fluids. ketchup ( or catsup) doesn't act like Newton's ideal fluid. It's a non-Newtonian fluid . (The scientific term for this type of non-Newtonian fluid is thixotropic. That comes from the Greek words thixis, which means "the act of handling" and trope, meaning "change".) Quicksand is a non-Newtonian fluid that acts more like your Ooze--it gets more viscous when you apply a shearing force. If you ever find yourself sinking in a pool of quicksand try swimming toward the shore very slowly. The slower you move, the less the quicksand will resist your movement. Physicists say that the best way to get ketchup to flow is to turn the bottle over and be patient. Smacking the bottom of the bottle actually slows the ketchup down!"
