The x2 Sport, An Underwater Jet Pack Controlled Using Two Wrist-Mounted Propellers
by Glen Tickle from Laughing Squid on (#QKY2)
The x2 Sport is an underwater jet pack controlled with two wrist-mounted propellers attached to a backpack that contains the system's batteries. The creators of the x2 Sport asked Olympic swimmers Jack Burnell and Roberto Pavoni to demonstrate the device in a pool, and the two were able to do barrel rolls and swim 50 meters under water in just 20 seconds.
