For the first time ever, I, Snorkel Bob, present Fresh Air Snorkeling. The MOFLO™ Snorkel [patented] succeeds where dozens failed in recent decades.

Cures Snoring!*
Enhances Potency!**
Grows Hair!***

Here's how it works—As you must know by now, the exchange of carbon dioxide (exhale) for oxygen (inhale) occurs in billions of cells called alveoli. These cells reside in the bronchial tubes and lungs, but not in the 4-6 inches from the trachea to the mouth hole—the stretch known as dead air space.
A primitive snorkel triples dead air space and results in rebreathing the same air, which is worse than wearing the same sox or not changing your underwear. Snorkelers can experience burning lungs & in time a heavy heart.
Now comes The MOFLO™ by me, Snorkel Bob, with fresh air on every breath. Thanks to Jarvic VII-style aortic valvulation and demarcation between in & out more tangible than that between church and state, I, Snorkel Bob, have once again CHANGED THE WORLD!
Because original ideas in Snorkeling come to me, Snorkel Bob. The MOFLO™ is $47
