    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/

    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.
