You can find this amazing rollercoaster at the Cosmo Land amusement park in Yokohama, Japan. The Vanish rollercoaster features a terrifying and exciting drop into an underwater tunnel. It looks as if the riders are plunging straight into a giant pool, with water splashing up around them as they dive in. This ride is definitely not for the faint of heart!
