Swamps In The American South Turn Into Shimmering Rainbows When The Light Hits Just Right

Summary: Did you know some swamps in the southern United States can turn into glowing rainbows? It sounds like magic, but it is actually science! Bald cypress trees drop their needles into the swamp water during the fall. As these needles rot, they release natural oils that float on top of the water. When the winter sunlight hits this thin layer of oil at the perfect angle, it creates a dazzling rainbow effect. It looks just like a colorful oil spill, but it is completely natural and safe for the environment. You can see this beautiful trick of nature in places like Virginia, Florida, and Texas, as long as the wind does not blow the fragile rainbow film away!
