For 25 bucks, Ft. Lauderdale locals and visitors can take a one-hour spin on HydroBOB, an underwater scooter that can be rented for joyrides at Hydrodome, a water-based adventure park that organizes parties and team-building events.

BOB stands for Breathing Observation Bubble and refers to the clear helmet that gives rides a 180-degree field of vision when they're operating the scooter. Equipped with an oxygen tank, the HydroBOB doesn't have to resurface during the one-hour ride, during which riders can easily manipulate the device with a motorcycle-like throttle. Unfortunately, the HydroBOB isn't yet able to brave the ocean or other fish-infested waters and is limited to swimming pools until a sturdier version is developed.
