I bet that would set my heart in or out of rhythm. I sure am glad he landed in the tank, not overshot it!!!!!!!!!!!!The Best Western in Rapid City had a WaterSlide and pool associated with their 257 room facility.The "slide" looked like a tube. You were completely enclosed as you slide down the convoluted slide. i heard, and this may be a rumor, a rather large sized man tried to slide down this slide and got stuck. They had to take the Slide apart to get him out.
Oh Lord! How embarrassing would that be? Sounds like something that would happen to me. They have slides like you described at some of the water parks around here. They look scary to me and they don't even shoot you out a half mile into a wading pool.
