Build a Rube Goldberg Machine

As a fun night-in, you can build a Rube Goldberg machine together. This is a contraption that serves basically no purpose. It is simply a delight in useless intricacy.

How convoluted can you make it?

As a practical guideline, the best machines are made up of a series of contraptions broken down into stages. These can be built separately, but near to each other.

That way, you can test each one without triggering the others. But once you are ready, you can connect them all and make a giant series of interesting interactions!
