Have you ever tried to squeeze honey or syrup out of a bottle at breakfast on a chilly winter morning? Do you notice that it’s harder to do that than on a hot summer day?

Viscosity is a properly of liquids that can be very important in very different applications—from how the syrup flows out of your bottle to how blood flows through the human body to how lava flows out of a volcano. In this project you will learn a little bit about viscosity by holding a marble race!
