The Vanish Rollercoaster at Cosmo World in Yokohama, Japan may not be the tallest ride in the world, it may not be the longest ride in the world or even the fastest, but one rather unique feature it does boast over other rides is the fact it plunges straight into an underwater tunnel! The rollercoaster journeys through the city skies of Yokohama before plunging 114 feet straight down into the pool of water below. If you suffer from a fear of heights and being trapped under water, this is one rollercoaster you will definitely want to avoid. The pictures alone made our palms a little sweaty!
