Introduction: Knex Ball Machine Element: Roll-Back Loop

Picture of Knex Ball Machine Element: Roll-Back Loop

Hey everyone,

Here are instructions for a special loop. You can make the drop longer if you want but not shorter, or the ball will not be able to go over the loop. It works 90% of the time, it's not too hard to build and is really fun to use. You can always watch te video to see it in action.

If there are any questions/ problems feel free to ask me in the comments below.

Thanks for watching/ building,

Thibault Art.
