Michael Jones McKean, professor at the Virginia Commonwealth University, created a machine that makes artificial rainbows out of natural materials. The machine uses high-powered jet pumps and custom fountain nozzles to spray recycled rainwater into the air in such a way that it forms rainbows. The machine is solar-powered and generates renewable electricity.

McKean is planning to install a larger iteration of his rainbow machine at the Bemis Center for Contemporary Arts in Omaha, Nebraska.
