\n\nAction films and cartoons share a common idea, well, many ideas, but I will call your attention to this familiar situation.\n\nOur hero, be he Bugs Bunny evading Elmer Fudd or a warrior on the run, encounters a river. To thwart pursuers, he plucks a reed from the surrounding vegetation and submerges himself with only the reed protruding above the surface. He remains stealthily submerged until the pursuers have passed.\n\nThere are also more than a few accounts in legend of various feats of escape that utilized this same breathing-though-a-reed trick.\n\nOur surface interpretation of this feat is that it is plausible, after all, the reed is operating as a snorkel and snorkels do a fine job of allowing one to breath while submerged.\n\nBut, let's look at the bare-bones physics behind this.\n\n[dfads params='groups=292&limit=1&orderby=random']\n

First:<\/h4>\nThe deeper we submerge, the pressure change prohibits us from being able to breathe non-pressurized air\u2014scuba tanks contain pressurized air. When we use a reed, we are attempting to draw directly from the atmosphere, a non-pressurized source. The external pressure on the chest makes it harder to draw (produce the suction) for a substantial breath.\n\nAt a depth of a mere one meter<\/strong> it is no longer physically possible to take that reed breath. And this holds for strong-lunged individuals and weak-lunged individuals alike. Most people find drawing a breath at even half<\/strong> that depth is quite difficult.\n

Second:<\/h4>\nThe air in the reed must be exchanged. As we increase the length of the reed we increase the difficulty of gas-exchange. We add to this the accompanying friction for every bit of length gain increasing our difficulty of draw which is already compounded by the external depth pressure.\n

Third<\/h4>\nReed diameter. Compare the experience of breathing through a narrow aperture such as a drinking straw and that of breathing through a snorkel. The snorkel's aperture is far easier on the draw.\n\nBut... there's the snorkel idea again.\n\n[dfads params='groups=292&limit=1&orderby=random']\n

Is not a snorkel essentially an artificial reed?<\/em><\/h4>\nOnly in appearance.\n\nSnorkel design takes in the above physical deficits.\n
    \n \t
  1. They have wide apertures for ease of draw.<\/li>\n \t
  2. The have short length to ease gas exchange.<\/li>\n \t
  3. The short length is also to compensate for the known pressure problem. Snorkels are designed to be used while you are face-down in water, essentially skimming along the surface not actually submerged. We see no extra-long snorkels because the designers know of the physical limitations (both biological and mechanical limitations) that would render the product dangerous.<\/li>\n<\/ol>\nWith the above in mind, we can enjoy our cartoons and if ever evading pursuers in water skip the reed. It is wiser to work your combat breath-holding, your \"splashless\" swimming tactics, and the whole inventory of aquatic stealth.\n\nClick Here For Stunnginly Vicious Self Defense Tips & Moves From Mark Hatmaker<\/strong><\/a>\n\n<\/div>","protected":false},"excerpt":{"rendered":"
