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.
