Rube Goldberg

A Rube Goldberg machine is a machine intentionally designed to perform a simple task in an indirect and over-complicated fashion. Our simple task that was assigned to us was to pour a bowl of cereal with at least 20 steps to get to this end-goal. Our team names was Third Times a Charm.

THE BOARD

We started this project with a blank mind and only a little bit of knowledge on who our teammates were. Me and my teammates, Corban Bishop and Alyssa Nelson, began to work on this project in the middle of September 2018 and we finished around the middle of October 2018. We finished our required steps (at least 20) and got to compete at the STEM Festival.

THE STEPS

The cereal theme my teammates and I chose was Lucky Charms. This meant we had to design the board and its steps to represent the Lucky Charms cereal. We decided to make the steps based on the marshmallow charms inside the cereal.
