What is snorkelling
Snorkelling is the practice of Swimming on or through a body of water while a circled tube called a snorkel, and usually fins. In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler to observe underwater attractions for extended periods of time with relatively little effort.
Equipment and care of equipment
for snorkelling you need a snorkel,gogles,fins and a wet suit if needed.
after use of the equipment it is good to rinse them in warm water so that they dont have sand on them and they dont smell.
Underwater science the ear and equalising, buoyancy
Ear clearing or clearing the ears is any of various manoeuvres to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure. This need can arise in scuba diving, skydiving, fast descent in an aircraft, fast descent in a mine cage, and being put into pressure in a caisson or similar pressure-bearing structure, or sometimes even simply travelling at fast speeds in an automobile.
People who do intense weight lifting, like squats, may experience sudden conductive hearing loss due to air pressure building up inside the ear. They are advised to engage in an ear clearing method to relieve pressure, or pain if any.
skills getting in and out of the water.
To go into the water when snorkelling walk in backwards in the water then put your goggles on, to get out of the water take of your goggles and walk backwards to get out
