Optical Illusion Shows Waterfall Appearing to Emerge from Rainbow in Brazilian Cave
A video from Brazil's Casa de Pedra cave shows a waterfall appearing to pour from a rainbow in the sky, creating a striking optical illusion. The water flows from a natural crack above the cave entrance, aligning with the sky when viewed from inside. A solar halo, caused by sunlight refracting through ice crystals, forms a colorful ring around the Sun, enhancing the visual effect. The cave, located in Alto Ribeira Tourist State Park, features a massive entrance framing this natural spectacle.
