Lost Island Waterpark in Iowa, US, is celebrating its 10th anniversary this year with the opening of a brand new water ride.

Wailua Kapua, which translates in Hawaiian to ‘purple river dragon’, is the name of a new 990ft-long HydroMagnetic Rocket water coaster, developed by ProSlide.

The attraction takes riders, seated in four-person rafts, 40ft up to the top of the first hill before they experience the first in a succession of drops that sees them reach speeds of up to 35ft per second.
