WATERFALL RAINBOW ILLUSION

Nature's magic! Waterfall appears to emerge from sky; breathtaking video from giant Brazilian cave leaves viewers amazed

A video filmed inside Brazil’s Casa de Pedra cave has captured an unusual sight, with a waterfall appearing to pour straight out of a rainbow in the sky. The footage shows water falling from a crack in the rock above the cave entrance, while a colourful solar halo circles the Sun and another rainbow-like arc appears nearby. Located in Iporanga, Sao Paulo state, the cave is part of Alto Ribeira Tourist State Park and is known for its enormous entrance, which rises around 170 to 200 metres high. Here is how the cave’s setting, falling water and atmospheric optical effects create the striking illusion.
