On a sunny day, fill a clear glass bowl with water and place it on a window ledge that catches direct sunlight.

Who doesn’t stop whatever they are doing when a rainbow appears as if by magic in the sky?  It's almost impossible not to be mesmerized by the bright translucent colors of red, orange, green, blue, indigo, and violet.

​Although rainbows are natural occurrences, they don’t happen every day. Maybe that's why there is something so special and captivating about them.

Most rainbows appear as arcs in the sky, but rainbows can show up in other shapes and other places. They may materialize in mist, clouds, waterfalls, water fountains, and across the spray of a lawn sprinkler.

Rainbows form when light bends as it passes through water droplets. They also can be created when light passes through glass, as is the case with a prism.

Here’s how to make your own indoor rainbow with water, glass and a little bit of sunshine...

Make Your Own Rainbow


Adjust the mirror so the light hits the mirror and reflects through the water so it can create a rainbow in the room.

Look around for your rainbow. Check walls, ceiling, and floor. If you don’t see it, keep adjusting the mirror in the water until you find your rainbow.

Put a small mirror in the water at about a 45 degree angle. Make sure the reflective side of the mirror is pointed toward the sun. The mirror should not be fully submerged.
