Uber can get you place on land, through the air, and on the water. Starting soon, they'll be going below the surface, too. ScUber is the world's first ridesharing submarine, offering some lucky riders the chance to see the Great Barrier Reef up close. For international riders, there's a contest to enter that includes a five-night trip to Queensland, Australia, while riders in Gladstone, Cairns, Palm Cove, and Port Douglas will have the opportunity to book a ride right in the Uber app. The sub will run from May 27 to June 18, 2019, with the equivalent of all ride fees going to the Citizens of the Great Barrier Reef to help support conservation efforts.
