Scuba diving is a popular pastime. Scuba is an acronym; it stands for “self-contained underwater breathing apparatus.” In the fifteenth century, Leonardo da Vinci designed an underwater diving suit. Functional equipment not developed until much later. The eighteenth century brought practical devices for breathing under water. Such as diving suits and diving bells. Wearing these suits, divers could breathe under water even though their mobility was limited. In the twentieth century, Jacques Cousteau and Émile Gagnan solved this problem. By perfecting the aqualung. The aqualung is a cylinder of compressed air. It is worn on the back and connected to a mouthpiece. With an aqualung, divers have both air and mobility. Since 71 percent of the earth’s surface is covered by oceans. Scuba diving opened up a whole new world.
