Fun DIY Cardboard Marble Run Ideas for Kids

How to Make a DIY Cardboard Marble Run a cool STEM experiment. Turn your cardboard box, toilet paper rolls & paper towel rolls into a fun cardboard toy for kids.

Creating your own DIY cardboard marble runs is a fun way to teach your kids to recycled cardboard and other items at home. In making a cardboard STEM challenge kids will learn to look differently at the items you throw away and think about how to reuse them.

Plus they’ll have a great time playing with this fun recycled cardboard toy.

What You Need

Here is what you need to make your cardboard marble run.

DIY Cardboard Marble Run Supplies to create your own run out of paper towels & toilet paper rolls. A fun STEM project for kids at home or school.
  • Large Cardboard Box
  • Several Paper Towel Rolls or Wrapping Paper Rolls
  • Several Toilet Paper Rolls
  • Hot Glue Gun (can use tape or Elmer’s glue too)

How to Make a DIY Cardboard Marble Run

Step 1

The first step is finding a box that will work for your marble run. We used a box we picked up at Costco with our order but you can use any long cardboard box you have.

If your box doesn’t have sides you will need to add sides to keep the marbles from falling out.

Step 2

Now layout your paper towel rolls and toilet paper rolls and decide where they should be glued down. This is the STEM part of the challenge deciding how to line up your rolls so that the marble will roll down into your hole at the bottom.

We added toilet paper rolls at the bottom to catch the marbles and used the paper towel rolls to guide the marbles down the run.

The fun part will be playing with this to see which works best for your marble run.

Step 3

To add more spaces for the marble to land beside the toilet paper rolls we added color tape between the toilet paper rolls. This will help with a game later to give different level of points for landing on different colors or into the toilet paper rolls.

Step 4

Cut a hole in your Marble Run Board to drop your marble for this fun STEM experiment at home.

Cut out a hole at the tops where you can drop your marble. You may also want to experiment with larger marbles or bouncy balls later so make the hole large enough for different sizes.

You’ll want the hole to line up with your top paper towel rolls so that when you drop it the marble will hit the marble run.

Step 5

Now that you have your layout of where you want all your rolls it’s time to glue.

Use hot glue to make a Cardboard Marble Run. A fun cardboard challenge at home.

We started at the bottom so that we made sure the rolls all lead to rolling the marble into the toilet paper rolls at the end. You could mark the box with a pencil where you pick up the rolls so you know where you laid it out before gluing.

We used a hot glue gun because the roll seemed to stay better. However, if you don’t have a hot glue gun you could tape the rolls by running a heavy tape through the whole roll.

Or you could try Elmer’s Glue. It won’t last as long but if it falls down you can just retry making your maze with a different pattern. Which might also be fun for the kids.

Cardboard Marble Run Challenge

Now create a fun STEM challenge out of your marble run. Kids will observe which roll or color space the marble ends up in the most.

Let the kids guess what they think will happen and record their observations in our free printable STEM Observation Chart.

Free printable Observation Chart for your Marble Run Cardboard Experiment.

On the chart, kids can record which size marble they used and where it landed. To do this add numbers on your marble run for each roll on the bottom. Kids can write down it landed on the #1 roll or landed on a color space in between.

At the end have the kids look over their observations and tell you what they discovered. Was one size marble better at landing in the rolls? Which spot did marbles land in the most? Why do you think the marble landed in that spot more often than other spots?

Marble Run Game

Once you’re done with your STEM experiment let the kids play a game. Use the numbers you added to the rolls for the STEM challenge as points. If the marble lands in roll #1 you get 2 points, #2 you get 3 points, #3 you get 4 points and so one. Also, assign each color a certain point.

After your observations you’ll have a better idea of which spots are harder and easier to land to help you assign the points.

Have the kids record their points and after 5 runs see which marble got the most points.

I hope your kids will enjoy these DIY Cardboard Marble run ideas as much as my kids have. It’s a creative way to recycle cardboard and make it into a fun STEM activity.
