Introduction: Knex Ball Machine Midnight

About: K'nex instructions. Youtube:

Sorry, not many pictures, but the video is worth 1,000 words.

This machine was built around my bed, this is a machine that took about 2 1/2 months.

It is 7ft tall, weighs about 55 pounds, and is so much fun to watch.

    I'm sorry, but how is this an instructable on how to make it?
    Also your video link is not working, this way you have to copy it to the browser.

    I don't think it's supposed to be a step by step instructable. There are plenty of posts on here that are just showing a creation, such as this one.

    For this contest it is,

    "Entries will be judged based on clarity, ingenuity, creativity, quality
    of presentation, and execution of the Instructable. So pull out all the
    stops and make your entry phenomenal, ingenious, and top-notch!"

    straight from the contest header.

    It is my personal belief that people shouldn't win lots of K'nex (check out the prizes) just because they have a lot of K'nex in the first place. I am amazed at some builds, and I have nothing against them. It's just a little unfair to us with not much K'nex, because we have to make up for all that gigantumness that having a lot of K'nex can give, with extra creativity. Anyway, which would you rather give a coin to, a guy who has 5, or a guy who has 20?

    I don't want to offend anyone, just that's my oppinion.

    Yeah, I understand what you mean. In general, it seems that the features and prizes go to either huge builds or things that have been done plenty of times before. (Phone racks...). And that medium sized, creative builds don't get as much attention. I just recently posted one such build, and slightly surprised it hasn't been featured or anything, considering that it is the worlds first knex fish feeder.

    Yet this contest IS about creativity, and I hope that the judges will take that into account during the judging process. Best of luck to you in the contest, and hopefully we both win something. (Your build is pretty unique!)

    To sarge hill, I buy stuff if eBay, I have spent around 185 dollars
