Introduction: K'nex Ball Machine Element: Rod Rolling

Some said it's impossible,

I just say it's realy tricky.

    It was part of a challenge on the forums here.

    another word for "knex expert" is knexpert kinda fancy

    Thank you.

    My 14 years of k'nex experience has paid off :p

    hey, it's in my ball machine flashback and it works about 95%!
    thanks for the idea.

    could you rebuild and post
    as it is super cool

    Once upon a time, there was a small 'contest' to roll a ball on a rod: https://www.instructables.com/community/Ultimate-knex-ball-machine-KingQueen/

    You should make something under it in case it does fall off. That way it would go on to another path.

    This was just to show it's somehow possible. When you implement it in a ball machine you could/should do that, yes.

    But I don't have a ball machine atm and don't have time/place for one.
    They just asked for this in the k'nex community here on ibles.

    Yeah I know, but this is for those who would put it on a ball machine.

    wow!

    that's pretty good, though I do think it would fail sometimes if you attached it to a lift

    It's like I said in the description on youtube;
    It fails a lot, it'll work a lot better if you only use one grey rod instead of 2.

    And you shouldn't let a ball come directly from a lift, more likely from a slow path.
