Introduction: Compact Separator: a K'nex Ball Machine Separator

Picture of Compact Separator: a K'nex Ball Machine Separator

Here are the instructions for the new separator on our K'nex ball machine Impossible. This separator isn't all our idea. Thibault Art originally came up with this idea on his ball machine Route 66 at 7:30, so all credit goes to him. We just made our own version and are making instructions for it. Have fun!

it separates out balls for a knex ball machine. The video should tell you more about how it works/what it does. :)
