Diverse Marble-Rolling & Lifting Machines

This video shows a half dozen or more marble rolling machines, labyrinths, and games. There are a couple of very novel mechanisms for raising the marbles back to the top of machines. One such device (toward the end of the clip) uses a pair of side-by-side serpentine ladders to pass the marble back and forth until it reaches the top. Another (in the middle of the video) uses a huge auger-style drill bit to raise the marbles! Ingenious.
