The rainbow is an important part of our culture. And a pair of my lab assistants are looking for some quick cash at the end of the rainbow. Of course, the one problem is having to wait for a rainbow to appear. Fortunately, there are ways to create a rainbow without having to wait on mother nature; all you need is to apply a little scientific know-how. Of course, I do not guarantee a pot of gold at the end of these rainbows!
