Viscosity

Overview

Beginning with maple syrup on a plate of pancakes, Walker sheds light on viscosity and how it decreases with an increase in temperature. His second lecture is on non-Newtonian fluids, which act a little weird, such as Slime and Silly Putty. For a grand finale, Walker thrusts his fist into a bowl of fluid corn starch–which doesn't spill because its viscosity shoots up.
