Scuba Diving Science

            Most people believe that all you have to do to scuba dive is strap a tank on your back and jump in the water. There is a lot more that that. When you dive into the water the water puts pressure on your ears the farther you go down. If you don't equalize you ear will get sharp pains in the ear drum. To equalize you plug you nose and blow through your nose or you can swallow. A adult with a certification can dive down to 60ft/ 18m. Also the farther you go down you start to lose color. The first color you lose when you go down is red. The number one rule of scuba diving is ALWAYS BREATH NORMALLY!!! Never ever hold your breath. Think of a balloon full of air. The farther it goes down the smaller the balloon gets. It expands when it goes back up. if your lungs are full of air and you hold your breath and go up then that can seriously hurt your lungs. You try getting certified and you can see beautiful reefs and fish. It is worth it.
