OverviewOverview

While using carts and ferris wheels in a While using carts and ferris wheels in a set sequence as a Rube Goldberg set sequence as a Rube Goldberg machine, we will make a bowl of cereal. machine, we will make a bowl of cereal.

How it works.How it works.

We used ferris wheels and carts to move We used ferris wheels and carts to move the different components around. Only the different components around. Only one act is required from outside of the one act is required from outside of the system and that’s the initial moving of system and that’s the initial moving of the cart. All other energies are either the cart. All other energies are either potential or kinetic. potential or kinetic.
