Attached to the demand end of the snorkel at the bottom of the barrel, the mouthpiece serves to keep the snorkel in the mouth. It is made of soft and flexible material, typically natural rubber and latterly silicone or PVC. The commonest of the multiple designs available features a slightly concave flange with two lugs to be gripped between the teeth (see Figure 9):

Snorkeling doesn’t require any training. If you are able to swim you’ll be able to enjoy the activity by simply slipping on your snorkeling gear and entering the water. Someone who has never snorkeled before can be a pro within minutes. More advanced swimmers can dive down a little ways while snorkeling, but they can stay underwater only as long as they can hold their breath.
While the name "bikini" was at first applied only to beachwear that revealed the wearer's navel, today the fashion industry considers any two-piece swimsuit a bikini. Modern bikini fashions are characterized by a simple, brief design: two triangles of fabric that form a bra and cover the woman's breasts and a third that forms a panty cut below the navel that covers the groin and the buttocks.
1969: First national standard on snorkels. In December 1969, the British Standards Institution publishes British standard BS 4532 entitled "Specification for snorkels and face masks" and prepared by a committee on which the British Rubber Manufacturers' Association, the British Sub-Aqua Club, the Department for Education and Science, the Federation of British Manufacturers of Sports and Games, the Ministry of Defence Navy Department and the Royal Society for the Prevention of Accidents are represented. This British standard sets different maximum and minimum snorkel dimensions for adult and child users, specifies materials and design features for tubes and mouthpieces and requires a warning label and a set of instructions to be enclosed with each snorkel. In February 1980 and June 1991, the Deutsches Institut für Normung publishes the first and second editions of German standard DIN 7878 on snorkel safety and testing. This German standard sets safety and testing criteria comparable to British standard BS 4532 with an additional requirement that every snorkel must be topped with a fluorescent red or orange band to alert other water users of the snorkeller's presence. In November 1988, the Austrian Standards Institute publishes Austrian standard ÖNORM S 4223 entitled "Tauch-Zubehör; Schnorchel; Abmessungen, sicherheitstechnische Anforderungen, Prüfung, Normkennzeichnung" in German, subtitled "Diving accessories; snorkel; dimensions, safety requirements, testing, marking of conformity" in English and closely resembling German Standard DIN 7878 of February 1980 in specifications. The first and second editions of European standard EN 1972 on snorkel requirements and test methods appear in July 1997 and December 2015. This European standard refines snorkel dimension, airflow and joint-strength testing and matches snorkel measurements to the user's height and lung capacity. The snorkels regulated by these British, German and European standards exclude combined masks and snorkels in which the snorkel tubes open into the mask.
Sister to neighboring Vieques, this tiny island 17 miles off the eastern coast of Puerto Rico is about as chill a place as you'll ever find. There are no big resorts, fancy restaurants, or pricey boutiques. What the place does have is empty beaches and fantastic snorkeling. The beaches of Carlos Rosario, Tamarindo Grande, Tamarindo, and Melones are all a part of the Luis Peña Channel Natural Reserve and a feeding ground for sea turtles and stingrays.
