Last week at Empow Summer Workshop in Concord we experimented with 2 classic do-it-yourself science activities. First was the Diet Coke and Mentos soda fountain- which, if you are wondering, works equally well with Coke Zero, Diet Pepsi and either mint or fruit flavored Mentos.
Next was experimenting with cornstarch and water. Mixing cornstarch and water creates a non-Newtonian fluid called an oobleck (named after the Dr. Suess book Bartholomew and the Oobleck) that has the properties of a solid or a liquid depending on the amount of pressure applied to it. Check out the video below for Mechanical Matt’s explanation and to see this unusual substance in action. You can learn more on the Science Learning Hub here at this link.
