The “rainbow” in the drop

We describe an apparatus that can visualize the creation of rainbows using a cylinder of acrylic glass. The apparatus allows one to observe rainbows up to the sixth order. A brief theoretical introduction and a method to quantitatively analyze the observation are discussed. A simple lighting system is described and its divergence is computed. The effect of light divergence on rainbow formation is analyzed.
