Introduction: Knex Ball Machine Element: Twin Arm

Picture of Knex Ball Machine Element: Twin Arm

Hey everyone,

Here are instructions for a simple element for 3 knex balls. 1 ball stays in the element while it waits for 2 other knex balls to come until the whole thing tips over. It's easy to build and works about 90% of the time. You can always watch the video to see it in action.

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

Thanks for watching/ building,

Thibault Art.
