Some said it's impossible,

I just say it's realy tricky.
the K'nex ball machine element: rod rolling is dumb but and i love your others ☺ <br> <br>
It was part of a challenge on the forums here.
You are a knex expert
another word for &quot;knex expert&quot; is knexpert kinda fancy
Thank you. <br> <br>My 14 years of k'nex experience has paid off :p
hey, it's in my ball machine flashback and it works about 95%!<br>thanks for the idea.
yeah that looks sick dude
could you rebuild and post<br>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/
Pretty nifty!
You should make something under it in case it does fall off. That way it would go on to another path.<br />
This was just to show it's somehow possible. When you implement it in a ball machine you could/should do that, yes.<br /> <br /> But I don't have a ball machine atm and don't have time/place for one.<br /> They just asked for this in the <a href="https://www.instructables.com/community/Ultimate-knex-ball-machine-KingQueen/" rel="nofollow">k'nex community here on ibles</a>.<br />
Yeah I&nbsp;know, but this is for those who would put it on a ball machine.<br />
That's cool! <br />
that's pretty good, though I do think it would fail sometimes if you attached it to a lift<br />
It's like I said in the description on youtube;<br /> It fails a lot, it'll work a lot better if you only use one grey rod instead of 2.<br /> <br /> And you shouldn't let a ball come directly from a lift, more likely from a slow path.
yeah<br />
