You can’t fly like Superman through the air. But you can get pretty close beneath the waves with the X2 Sport Underwater Jet Pack. It uses two trusters, one mounted on each arm, to propel you through the water at speeds of up to 6mph and depths of up to 30 feet, while a backpack provides the power. The attached analog throttle grip makes it easy to control, and it can run for up to an hour on a single charge, or way longer than you can hold your breath.
