âOobleck,â named for the mysterious green substance described in the Dr. Seuss classic Bartholomew and the Oobleck, is a non-newtonian fluid meaning it doesnât follow Newtonâs laws of motion. A non-newtonian fluid (like oobleck or silly putty) has a different viscosity depending on the force applied. By contrast, newtonian fluids (like water) have a constant viscosity at a given temperature. No matter how fast you stir them they never get thicker or thinner. Oobleck is a mixture of cornstarch and water.
Slime â sometimes called Gak,''Goo'', Oobleck,''ooze'',etc...â is a glob of goo that feels cool and creepy to the touch. In other words, it's gross enough for kids to totally love it. You can buy it at the store, of course, but you can save some money and make slime at home.
