Wooden marble run "marble theater"

The Marble Theater is a Marble Machine made from wood.
On the back site there is a crank, rotating the crank will let the marble roll to 5 different “acts” or courses.
Inside this device is a big gear with holes that lift the marbles up to the top. You can adjust the acts by moving the green lever.

See this video to see it work.
