Going fast down the water slide

Posted in News and Instructable updates by enthdegree on August 3, 2008

I have been thinking lately on how to go down a water slide the fastest (.The big kind that they have at the local YMCA s. ) If you ask them, the lifeguard will almost always tell you the same thing: “Put your hands above your head and get into tight streamline while crossing your legs and laying flat on your back.” Putting your hands above your head will expose your shoulder blades more, so that you are actually using them as a kind of skid. Crossing your legs lets you use your heel as one too. So, really, what they tell you makes pretty good sense: only three parts of your body are touching the slide at once, and your entire body weight is divided onto just three points ( I think? ). With this technique I can get down a 25 foot slide in about 10~12 seconds.

If you think about it, however, the water on the slide is only going one direction, so the more water that hits you, the more pressure there is against you. If you sit up straight, more water is hitting you and so you should go faster, right? Wrong. You are not streamlined, so even if the water is going the same direction you are, you won’t be able to cut through it as fast, and you want to go fastER than the water is going. Also, your body weight is divided over a larger surface. ( An upside-down cone of metal will go down the slide faster than a block of metal of the same weight. I think. )

All of this is just speculation, and I have almost absolutely no knowledge in the field, so don’t bet yer life on it cuz it might be totally bogus. :mrgreen:

    Hey!!! You can go ahead and start playing RunScape! They took the age limit off of the account setup process!

    Unfortunately, the privacy policy has not changed:

    “If we become aware that we hold or have inadvertently disclosed any personally identifiable information for any player aged under 13, it will be retroactively deleted from our system to ensure the protection of the child’s privacy.”

    So I still have to wait a few more months. )c:

    Raed about it here.

    What I MEANT,you big genius,is that before you could not setup an account unless you lie. They ask you your date of birth,and now I can use my real date of birth and create an account without any fake information! Before you had say that you were 13.

    What I said has nothing to do with the Policy!!!

    Hunter:

    “Jaggex games” ( The people who are legally responsible for runescape AKA the administrators ) has been known to ignore and even at some point encourage kids under the age of 13 to join.

    Here’s an interesting article on that: http://www.truthscape.com/html/ts_TheRealAgeofRuneScapePlayers.htm

    The privacy policy will always be lower level than the ‘setup account’ dialog. Jaggex, along with all the other online games ( At least the ones targeted to kids ) is forced to include a privacy policy that complies with the Children’s Online Privacy Protection Act of 1998.

    A few of the act’s main points are as follows:

    -A ‘child’ [ Rugrat under the age of 13] need parental consent if he/she/it wants to give out personal info [Info ppl can use to track you down to your own home to break in and kill you while you sleep] online.

    - If the website administrator [ Evil tyrant boss that has power over everything ever created in the game/website ] sees that someone under 13 is on their site, they must destroy the info if they can collect it. Or the account. Or the person.

    …and a whole lot of other uninteresting jazz that doesn’t really matter right now.

    So anyway, that act was made to keep minorz from seeing porn and stuff, which is good and everything, but as you can easily discern from above, was obviously written with much more purpouse intended. It does complete it’s job effectively [sometimes] although it can seem overprotective and condescending at times.

    It’s really just the result of a gaggle of big fat lawyers up there on capital hill trying to protect a few hapless kids who ‘don’t know any better’ .

    And I STILL think it should only comply to ppl under 10.

    I am going to wait until 13 until I make a move. Everything that I said may very well be totally bogus, but, as they always say, “better safe than sorry.”

  9. Hunter said, on August 4, 2008 at 23:23

    I see your point,but I’m still disappointed :-( :’( Oh,well. It’s only a few weeks.

    YIKES! I’m not sure I can take http://www.truthscape.com/html/ts_TheRealAgeofRuneScapePlayers.htm seriously! I got a “popup blocked” message from it!

    Orly? it says you should only get one in the FAQ. The ads are what keep the site up and running. I think.

    Hey! This has to do with the blunt body dynamics I was talking about from my work. Great post!

    thanks for the advice, but all you have to do is say that you are 13, a couple of weeks rarely influence somebodys maturity, I feel that the age limit is more of a guidline. If you still feel like you are doing something wrong, ask for perrmission from your parents.

    Thanks, ‘rodeo bill’! :D
