Wave pools are weird. They are in landlocked parts of the world and have been engineered by scientists to produce overwhelming levels of stoke. No matter how divisive it's hard to argue that they don't look fun. One man determined to explore the full spectrum of weird waves out there is Puerto Rico's Dylan Graves. The final episode of his series 'Weird Waves' Season 2 sees him sample waves of the artificial kind and finishes with a trip to the latest man-made creation in Palm Springs.
