How do insulated cups keep your drink hot? Neil deGrasse Tyson, with the help of comedian Chuck Nice, explains the physics of heat transfer, insulation, and why your Stanley cup can keep your drink cold in a fire. Learn about conduction, convection, and radiation. We break down methods to prevent heat transfer and how insulation works to keep the heat to one side. What does heat do when there is no air like in space? Plus, learn how the Apollo 13 mission used a trick with convection to save energy.
