LA Flyboard, Marina Del Rey

In just a few years of existence, flyboard riders have elevated the device from a waterfront curiosity to something of an art form. LA Flyboard's owners use the eponymous device to perform gravity defying stunts over the waters of the Pacific Ocean held aloft by jets that can reach heights of up to 30 feet. It seems like it might take time to gain such agility, but they insist the boards are easy to learn. With a few tips from them, a rider need merely strap on a board and practice for 15 minutes before being able to leap and dive in and out of the surf.
