The first patented water slide in the U.S. was the Water-Toboggan Slide, by Herbert Sellner in 1923 in Faribault, MN.
It consisted of a wooden slide which started with a down-ramp and then went out over a lake. People would sit in a wooden sled and slide down the ramp, where they would keep gliding along over the water for up to 100 feet.
Before that, however, a very similar contraption was seen in New Zealand during the 1906 International Exhibition, as part of the “Wonderland” attraction.
Water slides have been found in many amusement parks (and probably all water parks) ever since.
Innovations in software can now tell us how to space out riders so they never run into each other, or how high to make the wall on a curve to keep everyone in. Water slides are purely recreational, but they occasionally have serious consequences.
Computer models are being used to learn about water flow, friction, and how different masses will behave on a given slide. These models are helping cut down on accidents throughout the industry.
On some rides, like those with steep drops, heavier riders will go faster on average, and that's borne out by computer simulations. The deeply curved sides of some slides let you ride up on the wall as you turn, giving you a thrilling sense that you might fly out but keeping you safe inside.
The water slide shown in the figure ends at a height of 1.50 m above the pool. If the person starts from rest at point A and lands in the water at point B, which has a horizontal distance L = 2.58 m from the base of the slide, what is the height h of the water slide? (Assume the water slide is frictionless.)
