Check out our new site currently under development, combining the Biotechnology and Science Learning Hubs with a new look and new functionality. When buying a snorkel, some water lovers are surprised by the wide variety of options that are available for a fairly simple piece of gear. If you are a scuba diver, the more advanced snorkel features available may enhance your time in the water, but they are definitely not required. Fit: When trying out snorkels, make sure the mouthpiece is comfortable and does not pinch the corners of your mouth.
Maintenance: Much like your home's fire detector batteries, mouthpieces should be changed out from time to time, depending upon the amount of use. Quick-release device: Some divers and snorkelers see snorkel clips and snorkel keepers as a hassle. Semi-dry snorkels: If you are interested in reducing the amount of water that can enter your snorkel, consider purchasing a dry or semi-dry snorkel. NOTE: Dry snorkels are not manufactured with purge valves because they do not allow any water into the barrel. Folding snorkels: Many scuba divers who don't want the inconvenience of a snorkel's additional drag while at depth. Attaching a safety flag to your snorkel is a good idea for anyone who plans on swimming at the surface, be it a snorkeler or a scuba diver.
A snorkel lock attaches your snorkel to your mask strap and keeps your snorkel firmly in place when the it is in use. The last thing you want to do is find out on the beach or dive boat that something is wrong with your gear, and not have a way to fix the problem.
Using caulking around windows and doors is the easiest method to stop air and water leaks, either in or out. I tend to drag the caulking and then using my finger push it well into the crack I am filling.
Some have built in screwdrivers to drive in drywall screws, as well as a heavy end to drive in nails. If you do not want to do-it-yourself, check here for contractors in your area for just about anything from fixing your water heater to a whole house remodel. All projects should comply with your local building code regulations, permits and inspections.

The details and features can become overwhelming, but if you keep the following points at the forefront of your decision making, you're guaranteed to find the right snorkel for you. When shopping for a snorkel, make sure it is comfortable in your mouth and works well with your mask and doesn't interfere with your other scuba gear.
The silicone offers you a long-lasting mouthpiece that is flexible, offering the most comfortable fit.
Also make sure that the mouthpiece is flexible enough to fit between your teeth without you having to clamp down on it.
There is no right or wrong shape option, so long as the snorkel is comfortable and meets your breathing needs. The basic clip is typically an inverted iUi shape that attaches to your snorkel barrel and slides over your mask strap.
Quick-release devices allow a tab on the snorkel to slide into a sleeve that has been attached to the mask strap. Instead of the having to throw your head back while exhaling at a high rate, the purge valve allows you to keep your head in a neutral position while exhaling at a comfortable rate. This accordion-style material keeps the snorkel's mouthpiece out of the while the diver is at depth. Standard snorkels do not restrict water from entering the top of the snorkel tube if it is submerged. By carrying a save-a-dive kit, you can still safely enjoy your dive or snorkeling adventure just like you planned.

When searching for a snorkel, make sure it is comfort- able in your mouth and works well with the mask you plan on wearing in the water.


Divers primarily use snorkels during their surface swims to conserve the air in their tanks. Some mouthpieces are made out of other materials, but tend to be less comfortable and deteriorate faster than their silicone counterparts.
When placing your snorkel on your mask strap, make sure that the end of your snorkel is out of the water when you are face down in the water and that air freely enters your snorkel tube.
The quick release offers snorkelers and divers a method for donning and ditching their snorkels without requiring vast amounts of dexterity and a degree in mechanical engineering. It’ll be a great way to blow their little minds, especially since it’s so quick and easy to do. A snorkel mouthpiece, much like a regulator's mouthpiece, should rest comfortably between your upper and lower teeth; if you experience jaw soreness or fatigue during or after your snorkeling adventure, try relaxing your bite the next time you are breathing through your snorkel.
If your snorkel fills with water when you are swimming at the surface, the snorkel is either the wrong shape for you or the snorkel's placement on your mask needs to be adjusted. And once you’ve glow-ified your water, you can store it in a bottle and, unlike glow sticks, it won’t fade.All you need to do is take a non-toxic highlighter and cut it open to remove the ink-soaked felt inside. Regardless of the tube's shape, it should have a good diameter for the air to flow into; if the diameter is too small, you may struggle to fill your lungs with air. Slice that tube open to release the ink and then just soak it in water for a while or squeeze the ink out if you want it to go quicker. The payoff is that semi-dry and dry snorkels also may slightly restrict the amount of air that flows into the tube. Then you just need to put a UV light (black light) to it and it’ll light right up!Although the highlighters are described as non-toxic, and despite what the video says, I definitely wouldn’t recommend drinking this.If you want someone’s actual beverage to light up which they can still drink safely, just pour them a glass of tonic water and bring that to the UV light. Although the bright blue glow may make it look radioactive, we all know that tonic water is safe to drink.
Tonic water contains a chemical called quinine that comes from the bark of a specific tree; this natural-occurring chemical has actually been used to treat malaria for centuries. Even though there is such a small amount of the bitter-tasting quinine dissolved into the water, when under a UV light, it emits a fluorescent glow all on its own.Pretty cool, huh?
