I jumped from a 15 story platform (47 meters) into a lake at Lake Taupo, New Zealand. The first 2 seconds or so is cool, because it is complete free fall. The lake is rushing up at you and it gets the heart pumping. After the initial free fall, the bungee starts to pull on you and the g-forces start. The two or three rebounds caused by the chord are the only jarring parts of the jump.
