Hi there!

After 10 months of work, we're proud to present you our biggest k'nex ball machine: Impossible! This is by far our biggest k'nex ball machine ever, and has: 13 paths, 7 lifts divided into 2 networks. The whole thing runs on 2 motors, but a 3rd is necessary for an element. It is kind of confusing how the lifts are divided, so I'll tell you how it works. The first motor runs the top 2 arm lifts, and the wheel lift in network 1, and the chain lift in network 2. The second motor runs the first and second lift in network 2, the bottom arm lift in network 1, and the separator for network 1.

Some stats:

Height: 2.31 meters (7' 7'')

With and depth: 91 cm (3')

Number of pieces: 21,727

Number of balls: 20

Number of motors: 3

If you have any questions/comments, feel free to leave a comment or PM us.

This instructable is now an entry in the "Make it Move" contest. If you feel like it, would you vote for it? It would be much appreciated. :)

Thanks for watching/looking!
