Rube Goldberg Ideas: Tasks and Materials to Make Your Own Machine

Looking for Rube Goldberg Machine™ Tasks and Materials Ideas?

This article is written entirely to encourage ingenuity, creativity, critical thinking and problem solving.

The very best way to do all of those things at once is to give your kids some materials and let them create a Rube Goldberg Machine™.

Rube Goldberg: a comically involved, complicated invention, laboriously contrived to perform a simple operation. ~Webster’s New World Dictionary

A Rube Goldberg Machine™ is silly, and thoroughly enjoyable, to take a look at.

What I love so much about these machines is that they are all about learning in a non-traditional manner and they are just so much fun!Build your own Rube Goldberg Machine™! Use this great list of task ideas to choose the type of machine you want to build, gather some of the materials on our big list and make your own machine. Super fun learning opportunities throughout the whole process. Click to get the lists.

Rube Goldberg Ideas

There are Rube Goldberg competitions where the task is pre-chosen. Each team has to perform a very specific task.

It appears the contests are now going commercial. In 2017 the competition task is to apply a Band-aid and in 2018 it is pour a bowl of cereal (Cheerios.)

If you are interested in the official contests go here for more information.

There are a few criteria to keep in mind when creating your machines.

  • They should be funny.
  • They should tell a story.
  • They should use everyday objects and/or recycled objects.
  • They should be well-constructed.

If you are not familiar with these contraptions be sure to take a look at the resource links below before you get started. They will help you learn more about the process and give you a lot of great ideas.

Rube Goldberg Machine™ Tasks

Here are a variety of tasks from Rube Goldberg Machine Contests® in past years. Some of them were really challenging!

Rube Goldberg Activity Idea:

  • Talk about the different tasks listed below and and ask your kids how they would accomplish them.
  • Even if you don’t want to try to make them, talking how you might go about doing so really gets the wheels turning .
  • Work together to think of some crazy contraptions that would work.
  • You can even sketch them out – after all, that is what Rube did. He didn’t actually build the creations though, he just drew the comics.

Rube Goldberg Machine™ Materials

There are so many materials you can use when creating your invention.

Use things you already have around the house to start and add in items as you need them.

Here are our favorites.

THIS is the Coolest Item Ever to Add to Your Rube Goldberg™ Machine – Love it!

Some good material choices are:

    • LEGO Bricks – you can make things to knock down or build contraptions
    • paper tubes
    • funnels – use several for best effect
    • piping (clear is a great choice so you can see the ball go through!)
    • pvc elbows – for turns in tubing or to use to catapult a ball out of
    • tubing – flexible tube is a good idea for having liquid, marbles or other objects go through

Here are a few additional things we use in our Rube Machines. Click pictures to view items.

Making a Rube Goldberg contraption can be as complicated as you wish to make it or it can be delightfully simple. Kids of any age can participate in building one.

These are just some ideas for you – the sky is the limit.

Have your kids think up a mundane task and see if they can build a Rube Goldberg Contraption to complete the job.

Give it a try. I guarantee that Rube Goldberg Machines™ will provide an opportunity for fun and learning.

Hi Sheila,

This is a great site! My son has a task to create a Rube Goldberg style device where his end result is to get a golf ball onto a tee that is fixed in place. Do you have any suggestions for a final action that would be good to accomplish this finale?

Appreciate all your help!

Hi Pearl, I'm so sorry I didn't see this until now. I was ill. I suppose you have already figured out how to do this but just in case you have not, I'll give you an idea. If I had to get a golf ball onto a golf tee, I would try to have the ball roll down a tube or inclined plane and land on the tee. I'm not sure of the rules they set forth for this but if possible, I would have the tee positioned near walls or have something surrounding it so when the ball lands it stays on the tee. Thanks for stopping by and for your nice comment.

This is interesting. I have created multiple Rube Goldberg machines at school: for the G&T program and science class. I am doing the project again this year in science class, and I think that this was certainly helpful as a refresher. I have a suggestion for people in general: this is a kind of thing that is the most fun in groups. How I have done it in the past is that each person (or pair, in big groups) gets a section of the machine to work on, and do whatever they want in that part of the machine. It builds teamwork for each person to have to coordinate what they are doing with the person in front of and behind them.

Hi - Thanks for the great suggestion! I know a lot of homeschool groups who do these together as well.

What materials can we use for a lever??

Sheila Rogers

Thursday 2nd of March 2017

A simple lever can be made with any straight item such as a ruler and a pivot of some sort. So place the ruler on a block or a thick dowel and you have a lever. If you need something bigger, try a piece of board over an oatmeal container.

What are materials we can use for a pulley?

Sheila Rogers

Thursday 2nd of March 2017

You can purchase a pulley to use in your project and I have linked to a good one in the article. If you prefer to make your own pulley system try a hanger with a spool on it (you have to cut the bottom of the hanger to insert the spool) and use it with a piece of rope to pull your item up/down.

There are many different ways to make both levers and pulleys. Google them or google "simple machines" to learn more.
