Yellow Umbrella Opener

The machine starts off with dominos falling, rolling a marble down into the spiral/screw. The marble falls into a box triggering a pully to lift a stopper to release another marble down an inclined plane. This marble falls into another box triggering a set of pulleys that lifts another stopper and releases a marble down another inclined plane. That marble falls into a box activating the pullies in combination that releases a large marble onto a lever. The lever lifts on the left side due to the weight which pushes up a rod attached to the umbrella, causing it to open. The opening of the umbrella knocks over a domino, finally triggering a domino effect.
