Circular snorkel

    The new super-snorkel will allow swimmers to swim and breathe more easily without ever lifting their face from the water.
    The snorkel will be designed to fit around the head, allowing the user to take in air from the top valve while exhaling it through the mouth. The system will be arranged so that no spent air will remain in the device and no water will enter, and it will fit tightly around the head to stay securely in place without drooping.
