K'nex Ball Machine Contest - Elements Answered

Greetings!

I've decided to run a small contest, in the hopes of us folk here at instructables coming up with some new and exciting ball machine elements and lifts.

All you need to do is post a photo and description (video would be awesome too!) of your newfangled ball machine element or lift in the comments below. The criteria you will be judged by are originality, execution and aesthetics.

The deadline is October 31st, giving you a whole month to work on your elements/lifts. Judging will be done my myself, and the winner will be announced shortly after.

The winner will receive a 3 month Pro Membership, and if there are 10 or more entries, the winner will receive a 1 year Pro membership, and the runner up a 3 month Pro Membership.

Good luck to all!

-IaC

Update: Winner announced!

Judging has taken place! There were many good entries - I thank you all for your participation. The winner I have chosen is Martijnd95 with his concave bowl. He will receive a 3 month pro membership for his creation.

Thanks everybody!

well, the ball enters at the end of the yellow connector path and it rolls to the other end. when the ball touches the yellow rod it will turn it and the part under the arm won't lean on the blue rod, so the arm can turn and the ball leaves the element.

You could use that concept in reverse to make an unmotorised lift.

Hey!

I'll accept the spiral bowl, but the entries need to be brand-new - the lift is a few months old, so I'm afraid I cant accept it.

Thanks very much! You're the only entrant thus far.
