• Free time is all the remaining time.
• Snorkeling is peeking through life underneath water by swimming with the aid of a snorkel and mask.
• Bouyancy is the upward force of water on an object.
• Enhanced Cooling is the process of transferring the heat away from the body much quicker than air given in the same temperature.
• Hydrostatic pressure is the pressure exerted by the water at equilibrium due to the force of the gravity.
• Alexander the Great encouraged the development of the first diving bell.
• Leonardo De Vinci proposed and created the first contemporary snorkel.
• Benjamin Franklin came up with the idea of using wooden paddles attached to the hands and feet to help swimmers swim faster.
• Frenchman Louis de Corlieu invented the modern fins.
• A mask serves as the viewing device in appreciating the world beneath the water.

• A classic snorkel has the most basic part, the solid tube and the mouthpiece.
• A purge valve is a common feature of many snorkels.
• A dry valve is a very special valve on top of the tube that completely stops the water from entering the tube when a wave comes or when diving under water.
• A snorkel vest is small and inflatable, which provides buoyancy with floating on water.
• A swimming cap helps in keeping hair out of the snorkel and the face as well.
• A mask defogger helps prevent the mask from fogging up.
• Fogging is when the lens of mask becomes hazy or obscured with tiny droplets of moisture that are formed on the lens inside the mask.
• When camping, keep the campsite small and discreet.
• Be courteous; yield to others on a trail.
• Do not feed wild animals or birds as it is not their natural food; the food might damage their health or alter their natural behaviors and even expose them to predators.
• When camping, cat holes are dug (6 – 8 inches deep) for human waste and covered just the same with soil and weeds or leaves on top.
• Leave nature as you found them; do not take any plant, rock, or marine animal with you.
• Observe wild animals from a distance and they should be avoided during sensitive times such as mating, nesting, or raising the young.
• Camp at least 200 feet from lakes and rivers to protect the waters.
• “Pack it in, pack it out” means everything you brought should be brought back with you including left-over food or fruit peel.
• Keep fires small and use only sticks from the ground than can be broken by hand.
• Do not build structures or furniture or dig trenches.
• In case you decide to bring your pets along, make sure it is allowed and you can control them.
• Use existing trails or campsites; no need to build a new campsite that will alter the environment.
• Protect wildlife and protect your food as well by storing and securing the trash well.
• If fires are permitted, use fire rings or mound fires that are already set up.
• Never burn plastics or other substances that emit toxic fumes.
