There's nothing quite like a rainbow: fleeting, beautiful and natural, they're a rare little surprise of beauty from nature. But why should nature have the last say on when a rainbow shows up?
That's the idea behind Michael Jones McKean's artificial rainbow maching, which uses reclaimed rainwater and sunlight to create rainbows. It "uses a series of high-powered jet pumps and custom fountain nozzles to spray water into the air, creating the conditions needed for a rainbow to appear." If you want to see this bad boy in action, it's set to be installed at the Bemis Center for Contemporary Arts in Omaha, Nebraska next June.
