I got a jump for my 18th birthday and was really looking forward to it. It was a jump from a crane over a lake and you would dip your head in the water at the lowest point. The jump itself was ok but nothing I’d want to repeat in itself but once I reached the lowest point and the rebound hit me, my head felt like it was about to explode. I felt horrible for the next few hours plus my hair was wet from the dip. Thanks, just no thanks.
