These are terms you will usually come across in diving and aviation. To scuba divers buoyancy compensators are devices worn by divers to provide life saving emergency buoyancy both underwater or on the surface. The device can have features including a low pressure direct feed that transports gas from the diving cylinder to the BC. There can be an over pressurization valve that automatically vents the bladders if the driver over inflates the BC by ascending or injecting too much gas. It could also be a plastic or metal backplate to support diving cylinders.

In aviation, buoyancy can be affected by changes in air temperature and the density of the air. Lifting gas temperature can be affected by heating of the hull by the sun. Accumulation and changes in ballasts can happen in flight maneuvers. Fuel consumption is also a cause for change in buoyancy. It is therefore necessary to take steps to control the buoyancy to keep at a desired altitude.

Boating is a lot of fun but it also needs a lot of work. Spend time to make sure that the machine and equipments are in good shape. Make sure you explain safe operation to everyone on board before heading out. A lot of calls for help from boaters in trouble are due to motor problems.

The sport of paintball is a relatively safe game compared to others, if rules are followed. In the playing field, the players are constantly reminded of safety practices needed to stay safe.

The gun should never be fired without paint and should never be shot at someone who is not wearing protection.

The most serious danger in playing paintball is getting hit directly in the eye. This can cause permanent blindness. That is why paintball helmets are mandatory when playing the game. However protecting your other body parts, while not essential, definitely makes the game more enjoyable – and the players more daring.

What people do not know is that it is because of this tragedy that pushed Goodyear to find a way to attach rubber to other materials making it the first step in making of what we know now as inflatable boat.

Inflatable boats are lightweight with high capacity, has flexible rubber tubes inside for pressurized gas and are made to ensure portability. Inflatable boats can be deflated or packed. Though it may have been originally used to replace wooden lifeboats that took up too much space on the cargo ship but, today, there are different uses for them such as water skiing, commercial fishing, and, due to its durability and strength, it is also used in the military for covert operations.
