Gizmo Knex ball machine (Piston style lifts)

Hello all, thanks for checking out this video. This is my first ball machine, which I completed in under 2 months. I had a bunch of Knex lying around, and was checking out other ball machines people were building, and decided to make one.
You may notice that the "return track" near the beginning is familiar, as I got that Idea from the "Metropolis" machine. Also part of the carnival track idea was from that same machine.
This ball machine is all about the balance. The only way to get the Knex ball to go through 4 loops was to have them loosely attached to the machine, while the entire machine was only held up by one support pillar, enabling it to sway back and forth as the ball whips through the loops adding momentum to the mix.
I would love to add more but as of now, I ran out of Knex. I do have a lot of other great original track ideas and will post if I get a hold of any more Knex.

The track being played is "funeral for a friend - Dream Theater"
