Machines!
machines use power and having several parts with a function and together performing a particular task. The Rube Goldberg Machine kind of worked it hit the easy button but every time we did it the machine fell apart in some area, I think we should’ve made it so the wood and railings could be more sturdy. Examples of simple machines are wheel and axle which makes it easier to move things around, a screw which can hold things together, and a wedge which can pull things apart.
