Rainbows are such an incredible thing to witness, made all the more so because they often feel like a rare treat. This video shows you a whole new view of this natural phenomenon: watch as a rainbow forms over a lake and reflects back up.

But how are rainbows formed, exactly? It’s simple science: light passes through the air and bends as it passes through water in a raindrop. The colors are formed because the raindrop acts as a prism.

Raindrops aren’t the only thing that can create all those beautiful colors. Take a look at how bacteria create a dazzling display at Yellowstone National Park’s Grand Prismatic Spring.
