I made a Rube Goldberg machine to harvest reeds! I could've done just one reed, but Rube Goldberg machines are supposed to be obnoxious, not inefficient. The machine contains 14 unique components, in addition to the button, redstone, and pistons. I believe that my machine uses more unique mechanics to transport the signal than any other Rube Goldberg machine made in Minecraft. I don't know whether or not I have the most complex in terms of total components, including repeated devices. All of the components in order, are:
