The task was to design a Rube Goldberg Machine. The ultimate goal is to raise the flag.

There are small balls inside the starter, as long as one of the small balls smoothly into the rotation orbit, even if the startup is successful. This is designed to increase the fault tolerance of the machine.

At the bottom of the spinning orbit is a glass ball, and the iron ball hits the glass. The glass ball takes advantage of this opportunity to enter the slide wall.

The slide wall was originally designed to run from the top down, but it turned out to look better from the bottom up.

The last glass bead in the slide wall will destroy the balancing device, and the three glass beads from the balancing device will enter the paper cup of the flag raising device.

Finally, as the weight increased, the cup slid and the flag was raised
