Leslie's cube is a classic demonstration of the emission of thermal radiation. The cube is heated to a uniform temperature by filling with water. The side of the cube are painted different colours: Shiny, matt, white and black.
In this video a thermal imaging camera (FLIR ONE) is used to view the Infra Red (thermal radiation) emitted from each of these surfaces.
