"Sunsets are red, Skies are blue, and Clouds are white. If you want to know why this is so, Scattering is right."

The Blue Sky exhibit, another exhibit made for NCAR by the Exploratorium Museum, lets visitors scatter light to prove this saying is true. It uses concentrated gelatin to produce enough scattering in such a small length (less than a meter) for you to see blue.
