What does the snorkels?

A snorkel is a device that allows a person to breathe while their head is underwater. It consists of a tube that extends from the mouth to above the waterline, and a mouthpiece that is held in the mouth. When a person breathes in through the snorkel, air is drawn in through the tube and into the lungs. When a person breathes out, the air is expelled through the tube and into the water.

Snorkels are used by swimmers, scuba divers, and other water sports enthusiasts. They allow people to stay underwater for extended periods of time without having to come up for air.

How does a snorkel work?

A snorkel works by creating a pressure difference between the inside of the tube and the outside of the tube. When a person breathes in, the muscles in their diaphragm contract and create a negative pressure in the lungs. This negative pressure draws air in through the snorkel and into the lungs.

When a person breathes out, the muscles in their diaphragm relax and the pressure in the lungs increases. This increased pressure pushes the air out through the snorkel and into the water.

What are the different types of snorkels?

There are many different types of snorkels available on the market, each with its own unique features. Some of the most common types of snorkels include:

* Dry snorkels: These snorkels have a float valve that prevents water from entering the tube. This makes them ideal for use in rough water or when swimming at the surface.

* Wet snorkels: These snorkels do not have a float valve, which allows water to enter the tube when the person breathes out. This makes them easier to purge (clear water from the tube), but they can be more difficult to breathe through in rough water.

* Full-face snorkels: These snorkels cover the entire face and allow people to breathe through their nose and mouth. They are ideal for people who want a more comfortable and natural snorkeling experience.

How to choose the right snorkel

When choosing a snorkel, there are a few things to keep in mind:

* The type of snorkeling you plan to do. If you plan to do a lot of surface swimming or diving in rough water, then a dry snorkel is a good option. If you plan to do more relaxed snorkeling, then a wet snorkel may be a better choice.

* Your level of experience. If you are new to snorkeling, then a full-face snorkel may be a good option. These snorkels are easier to use and can provide a more comfortable experience.

* Your budget. Snorkels range in price from a few dollars to over a hundred dollars. The best snorkel for you will depend on your budget and your individual needs.

How to use a snorkel

To use a snorkel, follow these steps:

1. Put the snorkel in your mouth and hold the mouthpiece between your teeth.

2. Breathe in and out normally.

3. If water gets into the tube, blow it out by forcefully exhaling through the snorkel.

4. Keep the snorkel above the waterline when you are not using it.

Snorkeling safety

Snorkeling can be a safe and enjoyable activity, but there are a few safety precautions that you should take:

* Snorkel only in areas that are safe for swimming.

* Never snorkel alone.

* Be aware of the currents and waves in the area where you are snorkeling.

* Do not snorkel in deep water or in areas with strong currents.

* Avoid touching or harassing marine life.

* If you experience any problems, signal for help and return to shore immediately.
