When building our machine, we learned, as a team, the effects of procrastination and the benefits of time management. Our team of 10 understood the concepts that we constantly needed to use. For example, when building the stands for our main prop, we had to use the Pythagorean Theorem. During our machine run, we understood the meaning of the word “Failure” and the quote from Yoda in The Last Jedi; “Failure, the best teacher is.” Our team, through constant trial and error, realized how much effort a Rube Goldberg machine really takes.
Our machine, consisting of a whopping 32 steps, are all made of simple and complex machines. We tried to minimize our space usage, making use of the 10x10 space provided. We built an entire door and a wall just for the skit alone. Our creativity exceeds limits, as we used common materials such as cardboard and plywood to make the prop. We calculated the time spent into our machine, and attained a total of over 103 hours and $126.
Our machine also relates to our skit. The steps do not go in a circle as usual Rube Goldberg machines, do but rather takes sudden twists and turns that most viewers wouldn’t expect. Our machine uses baseballs and baseball bats since some people watch a sport during breakfast. Our entire machine is designed our team and every part is hand built. no items were pre assembled. In the skit, time does not work, but our machine does. Our machine relays in under 30 seconds. Our theme remains solid and consistent throughout our skit and machine.
We thought for a while on what the theme of our skit would be, and after numerous days of debating, we had finally decided to center the skit, and the machine, around time travel. In our skit, we included inside jokes from last year’s competition, and we aim to get laugh(s) out of the audience. Our skit, though comical, does not offend any races in any way, but rather makes the characters, who are from different eras and places in time, work together to achieve a common goal, to pour a bowl of cereal.
