A snorkel is a tube that allows a person to breathe while their face is underwater. It is typically used for recreational activities such as snorkeling, free diving, and scuba diving.
To use a snorkel, the person places the mouthpiece in their mouth and inhales and exhales through the tube. The tube extends above the surface of the water, allowing the person to breathe in fresh air while their face is submerged. The tube is typically fitted with a valve or flap at the top to keep water out while the person is underwater.
The snorkel also has a flexible joint or “curve” near the mouthpiece, which allows the person to tilt their head back and look up while keeping the mouthpiece in place. This allows them to keep their face in the water while still being able to breathe.
Snorkels are generally very easy to use and can be a fun and convenient way to explore the underwater world.

Types of Snorkels
There are a few different types of snorkels that are commonly used for recreational activities such as snorkeling, free diving, and scuba diving. These include:
- Traditional snorkel: This is the most basic type of snorkel, and it consists of a tube with a mouthpiece at one end and a flexible joint or “curve” near the mouthpiece. Traditional snorkels are generally easy to use and are suitable for a wide range of activities.
- Dry snorkel: A dry snorkel is designed to keep the top of the tube dry and prevent water from entering the mouthpiece. This is typically achieved through the use of a valve or flap at the top of the tube. Dry snorkels are often preferred by snorkelers and scuba divers because they offer uninterrupted breathing and can help to reduce the risk of inhaling water.
- Semi-dry snorkel: A semi-dry snorkel is similar to a dry snorkel, but it has a splash guard at the top of the tube instead of a valve. The splash guard helps to deflect water away from the snorkel and prevent it from entering the tube. Semi-dry snorkels are a good choice for snorkelers who want some protection against water entering the tube, but who do not need the full water-blocking capabilities of a dry snorkel.
- Purge snorkel: A purge snorkel is a type of snorkel that has a one-way valve near the mouthpiece that allows water to be easily expelled from the tube. This can be helpful if water does enter the snorkel, as it allows the user to clear the tube without having to remove the mouthpiece. Purge snorkels are generally easy to use and are suitable for a wide range of activities.
Overall, there are a variety of snorkels available, and the best choice will depend on the specific needs and preferences of the user.
Can you go completely underwater with a snorkel?
Yes, it is possible to go completely underwater with a snorkel, as long as the top of the tube stays above the surface of the water and you continue to breathe in through the mouthpiece. However, it is important to note that a snorkel is not designed for extended periods of time underwater and is not a substitute for scuba diving equipment.
How does a snorkel keep out water?
A snorkel is designed to keep water out while you are using it by using a valve or flap at the top of the tube. This valve is typically located near the mouthpiece and is designed to seal the top of the tube when you inhale, preventing water from entering the tube.
When you exhale, the pressure in the tube decreases, allowing the valve to open and allowing the exhaled air to escape. This process helps to keep the tube dry and prevents water from entering the mouthpiece.

This is typically achieved through the use of a valve or flap at the top of the tube that seals the mouthpiece when you inhale, preventing water from entering the tube.
Why do snorkels fog up?
Snorkels can fog up for a number of reasons. One of the main reasons is temperature difference between the air inside the snorkel and the air outside the snorkel. When the air inside the snorkel is warmer than the air outside the snorkel, moisture in the warmer air can condense on the cooler surface of the snorkel, causing it to fog up.
How long are snorkels?
Snorkels typically range in length from about 30 centimeters (12 inches) to about 60 centimeters (24 inches). The length of the snorkel can vary depending on the specific model and the intended use of the snorkel.
Shorter snorkels are generally preferred by recreational snorkelers and free divers because they are more compact and easier to use. They are also typically less cumbersome and can be more comfortable to use for extended periods of time.
Longer snorkels are generally preferred by scuba divers because they allow for more flexibility and can be more comfortable to use with diving equipment. They are also typically more durable and can withstand the pressure at deeper depths.
Do you really need a snorkel?
Snorkels are typically used for recreational activities such as snorkeling, free diving, and scuba diving. While a snorkel is not absolutely necessary for these activities, it can be very useful in certain situations. For example, if you are snorkeling in an area with strong currents or waves, a snorkel can allow you to remain more stationary in the water and can make it easier to breathe while you are exploring.
