17 Story Water Slide?

This doesn't seem right or even possible.  The video is pretty cool.  17 story tall water slide that is pretty much a straight drop.  And then a bump afterwards...which as I thought about it, you'd be going so fast (~60 mph) that how would you not take flight coming off that hump?  And the slide is open-air, nothing to hold you in! Maybe it's the weight of four people in the tube? Too many questions.  Opens this summer in Kansas City.  Who's in!?


  1. Nobody related to us!!!!!!!!!!!!!!!!!!!!!!!!!

  2. Thanks this post completely diverted my last 30 min.

  3. If you didn't catch it, the name of the slide means 'insane' in German. I thought that sounded pretty accurate. I was also amazed by the height and drop angle so I ran some 'what-if' calculations and here's what I found:

    Using the two best side-angle photos I could find of the slide I measured the base, start-the-drop, and return-to-earth-points of the triangle. Nicely worked out to be a 30,60,90 triangle. Which means ZOOM. Thanks to BareNakedLadies we all know that a regular free fall results in acceleration of 9.8 m/s^2 This slide (in a frictionless world) generates ~ 7.2m/s^2. The report 178 foot drop? It takes 3.8 seconds. (v. the 3.3 seconds if you just bailed off the side).

    Adding in the friction muddies things up a bit since we don't know what it's made of exactly. Assuming some poly-something and rubber with water lubricating we're looking at coeff of ~ .2 to .1 (skates on ice = .04, which you can also achieve with teflon on most surfaces). This slows us down, but not much: 7.26 m/s^2 or 80mph at the base.

  4. whoops. the frictionless acceleration is actually 8.5.

  5. :) I KNEW when I was writing the post and posed that question that you would attempt to solve for X.
    Love the problem-solving.
    So here's the follow up question...if going 65 mph will a tube achieve seperation coming over the top of the second hump.

  6. Exactly why none of you will be on it.
