Propellers to the Fists! Wrist Thrusters for Auto Skin Diving

If you’re an experienced snorkler, you probably wear fins for propulsion, and a snorkel to help you breathe. If, however, you simply like to make fun and useful gadgets, and would rather not bother with “manually” swimming, then this set of arm propellers should be interesting.
