snorkels

A snorkel is a tube used for breathing air from above the water surface while a person’s face remains submerged in shallow water. It is commonly used for snorkeling, a recreational activity that combines swimming with observing underwater life. The device allows the user to breathe without lifting the head out of the water.

Construction and components typically include a flexible or rigid tube, a mouthpiece, and sometimes a valve or purge mechanism. The mouthpiece, usually made of silicone, is held between the teeth or lips. The tube, often made of plastic or silicone, may be straight or gently curved. Most standard snorkels measure about 30 to 40 centimeters (12 to 16 inches) in length, with shorter options available for children or performance-oriented diving.

Design variations focus on water management and comfort. Dry-top snorkels feature a float valve at the top to seal the tube when submerged, helping to prevent water entry. Semi-dry tops provide splash protection but may still admit some water. A purge valve near the lower end allows the user to expel water by exhaling sharply. Some models include flexible sections or mouthpiece configurations to reduce jaw fatigue and improve fit.

Usage and care: the snorkel is worn with a mask, holding the mouthpiece between the teeth while breathing through the tube. Clear water by exhaling through the mouth or nose. After use, rinse with fresh water to remove salt and sand, then dry away from direct sunlight. Proper fit and hygiene are important to comfort and safety. Snorkels are intended for surface breathing and are not substitutes for proper diving equipment in deeper or hazardous environments.
