I cannot explain the feeling, but it must be a true adrenalin rush that last at least few minutes. The thought alone that you may get pulled over the edge at any given time can get you excited to a point of disorientation. Jumping in will certainly add to the experience but going in gently might be the best way.
P.S. There are trained lifeguards on site to keep you safe, or should we say to keep you from plunging into your death!
