Build Your Own Underwater Breathing Device [VIDEO]
It's the ultimate DIY (Do It Yourself) project for the weekend. Learn to build your very own underwater breathing device! This thing will completely change short diving and snorkeling. You can't go too deep with this homemade invention, but you'll be able to extend your time underwater in the swallows. When and if I ever return to the beach I think I'll build one of these and bring it along.
