This is my new (and first) k'nex lift system. I came up with this idea, because the physics teacher was showing us the effect when anything that's heavy (a hammer) hits a light - weight thing. (a small ball) So I made that system with k'nex, and this is the result.
In this lift, a rotating arm goes up, and it comes down real fast, sending the ball up the incline.
The one in the video is a bit different, the one in this Instructable is better.
Hope you guys like it.

Step 1: Parts List
orange tube connector - 6
small grey gear-1
small wheel band-4
And, of course, you'll need k'nex balls and tubing
Step 2: Base
Step 4: Left Tower
Step 5: Motor
Step 6: Hammer
Step 7: Finished!!!
1. The new k'nex balls (the big ones) comes higher than the old ones: If you use them both, be careful at the top of your hill: the big balls could fly off the track.
2. Attach the track as much as possible, this is to save speed, and to reach higher. Also support the track good: It mustn't be unstable, the balls slow than down quickly.
3. If the arm goes stuck on the system that let 1 ball / time go, make the second and the third picture.
4. If the balls are going to be launched off the entrance path, make it longer. If the balls don't pass, wait till other balls arrive. That balls will push it trough the system that block balls.
