|U.S. Patent Issued In 1982.|
"In most fires, it's the smoke that will get you, and a source of fresh air can be a life saver. So our inventor designed a way to snake a snorkel through the zigs and zags of your toilet so you can breathe sewer air instead of smoke. Here's our question... couldn't he have just as easily invented the Faucet Snorkel instead?"
I suppose just leaving a bathroom that's filled with smoke is too easy for some people.
