(PotatoSalad67 says) the best way to test it is to take it out on the water and try it in shallow waters.
Wear the PFD in shallow water or a swimming pool.

The easiest way is to place it in a large container of water. There are more complex, scientific ways to test buoyancy, but this requires the use of modeling computers.
A metacentric diagram is a vessel (ship) stability diagram that shows the relative positions above and below the metacenter of the center of buoyancy and the center of gravity, respectively. Use the link to the Wikipedia article to view one and see how it looks. Follow along and see how it works. When a vessel floats in water, its center of gravity is below its center of buoyancy. That allows gravity to pull down on buoyancy from below the bouyancy to pull up on gravity from above (if it is permitted to say it that way). If the center of buoyancy slips below the center of gravity, the vessel will roll over. Visualize that. And the closer the two centers are, the less stable the vessel. That is, the more prone to rollover it is. The "sweet spot" between the centers of buoyancy and gravity is the metacenter. It's important in evaluating a ship's stability.
A marge ship, like an ocean liner, may be incredibly heavy. But the weight of something isn't the only thing that will determine if it sinks or floats. Buoyancy is also very important. Think about when you're in a pool and you hold your breath - you can actually float on your back for a little while. this is because the air in your lungs is providing you with buoyancy - essentially pushing you up out of the water*. Well, ships operate the same way - the inside of a ship is mainly hollow and filled with air, giving it the buoyancy necessary to float. * - Coincidentally, this is how hot air balloons work, too. The hot air in the balloon is lighter than the air around it, and provides buoyancy. Science!

Have everyone wear an appropriate PFD at all times.
the objects that are buoyancy are the objects that have the force to rise or to float in any way.
Using an oral thermometer is the best way to check your temperature.
Attached the engine shut off line securely to your wrist, life jacket or pfd
buoyancy makes you float up more. If you are in a swimming pool you realise that you won't fall down all the way down. That is buoyancy
The best way to check if a person is uncouscious is to induce pain to the subject and check for any reaction. A sleeping person is sure to wake up but not a uncouscious person.
The best way to check rates is to go online or call one of the brokers at a toll free number. Rates can vary daily so check often to make sure you have the best rate locked in.
Yes there is a Best Buy located in Federal Way, Washington. For the exact location you can check the phone book. For another Best Buy, you can check your book as well.
both....and it depends what you are looking to measure if you are looking to measure buoyancy by comparing the two salts then this is the way to do it.
