Many ball machine builders (including me!) use the same basic idea of an element I call a Seesaw. For this element, a ball rolls back and forth on the curved track until it stops. Then the dumper releases the ball. I made an Instructable for my version of this Seesaw element. Below are the link to my Instructable, the video and some pictures.

Seesaw- A K’nex Ball Machine Element

I made another ball machine element and an Instructable for it.  I call the ball machine element Trick Flip-Flops.  It looks like an element containing normal flip-flops. However, I call it Trick Flip-Flops because the flip-flops are weighted on one side and go back into place once triggered by a ball.

Sorry there is no video.  I just couldn’t get the element to stand up on its own for a video.  It will be in my next ball machine, though.  You can see it in action then.

Below is the picture and link to the Instructable.

I published my first Instructable for a K’nex ball machine element.  For my first Instructable, I decided to do a simple element.  I call the element The Catch Basket Zigzag.  Here is a link to the Instructable:
