The Fun Part There is nothing like breathing underwater for the very first time. It takes a little getting used to –after all, human beings weren’t designed to do that – but after a few minutes of awestruck wonder, most participants realize how easy scuba diving really is. The biggest challenge instructors have with the Discover Scuba Diving program is not coaxing participants into the water, but coaxing them out when the program is over. The fun part? It’s all fun!
