Aren’t rainbows just magical? Well, we know they are, but there’s a lot of interesting science behind them. These colourful marvels appear when light strikes water droplets, creating a natural prism effect. When found out in the world, they are a product of refraction of the sun’s rays, so you will always find them opposite from the sun’s position in the sky.

Hawai’i is one place where you can routinely witness the magic of rainbows. At Pu’uhonua o Honaunau National Park on the Big Island, a combination of a mountainous terrain, clear air, and wind helps create the perfect conditions for rainbow sightings.
