Contest FAQ's

We do a lot of things at the Institute and get a lot of questions. Here are some of the most frequently asked. Not seeing your question here? Contact us.

Does our machine have to complete the task?

Yes. The last step in your machine must complete the annual task.

Can you explain how to "Build a Lunchable's"?

To complete this year’s task, you will need to stack your Lunchable meal or snack as the final step of your machine. Check out Lunchables launch videos (found on our YouTube channel) for the 2023 RGMC and see how other Rube enthusiasts “Build a Lunchable’s”! And to get inspired about how to add theme and story to your machine, check out the many different Lunch-a-builds you can build at!

How big can we build the machine?

Any size. You can build on a table-top, in a room or in several rooms, in and out of buildings, or totally outside. Anything you can dream of! Just make sure we can follow the steps of your machine as it runs.

Is there a minimum or maximum step count?

This contest has no step limits. We do however encourage you to keep your machine runtime, including your introduction, under 4 minutes.

What kind of introduction do we need for our machine?

Let us know who you are, where you're from, the theme of your machine, and whatever else you'd like us to know before we watch your machine in action. But please do not walk us through the steps - we will see all of them in your machine run.

How do we film our machine?

Most people use their mobile phone to film, but any camera that shoots in clear, high quality, digital video is good. Things to remember when filming:

- Lighting: make sure that the light is good when filming so we can see your machine

- Perspective: shoot horizontally

- Filming: make sure to follow each step as the machine runs so we can see it

- Editing: we prefer to see your RGM in a single pass with no edits. Sometimes this isn't possible, but try!

- Task: always focus on the final step in your machine, that shows judges that you've completed the annual RGMC task

How do you judge the machines?

In this international competition we look for the most creative and entertaining Rube Goldberg Machines. Wow us. Try not to rely solely on chain reactions that we've seen before like marble and domino runs. Use everyday objects in your transfers of energy that engage and surprise us. And if you can, make us smile. The funnier your RGM, the better.

How do we make our machine funny?

Funny usually begins with the theme of your machine. Try to tell us a story through your RGM. One of the funniest machines we've seen in competition told the history of the world, from the Big Bang to the apocalypse - and in the end completed the task to WATER A PLANT. Just from the get-go, that machine was funny! And as your machine runs, it should tell a story in the most ridiculous way possible. Try to keep in mind that story-telling is usually done in 3 acts and unfolds in a similar way to a chain reaction. The first act is an introduction and the problem is identified. The second act is where the problem peaks. And the third act, through a series of heroic actions, the problem resolves! Funny can take the form of adding people into your machine, or employing the family pet to participate. And finally, the more random the objects in your machine, the funnier the machine will be. Get inspired by countless Rube Goldberg Machines on our YouTube channel or go to the gallery of Rube's invention cartoons. There's no shortage of "funny" in the world of Rube Goldberg!
