This is actually a science project I did when I was in school but I remembered it being so fun, I introduced it to my kids one very wet weekend. They had a ton of fun rearranging the path for the marble to run down. It’s great for them to learn about scientific discovery this way – sometimes one way doesn’t work, so you have to problem solve and think of another way to solve the problem of getting the marble into the box.


  • 6 empty toilet rolls
  • 1 small box (not seen in the picture)
  • 1 marble
  • sticky tape


  1. Clean the toilet rolls from any scraps of paper left on them.
  2. Cut strips of sticky tape and double side them. Stick them to one side of the toilet roll, then stick the toilet roll to the door. Do this for all the toilet rolls.
  3. Have your child figure out a path for the marble to run down and place the box on the ground where they think it will land.
  4. Once the path has been arranged on the door, have your child place the marble in the topmost toilet roll and see where it runs to. If it lands in the box - fab, see if they can make another path. If not, have them rearrange the toilet rolls until the marble runs true.

Notes... If you have small children, substitute the marble for a pom pom. It falls slightly slower and doesn't run so away if it misses the box. Plus, if you have wooden floors, it is much less noisy!

  • easy and fun for the holidays that is sure to provide hours of fun!


  • It is like an obstacle course


  • Great activity to keeps kids busy. Simple yet effective


  • Genius. Not only are you using up old toilet rolls in an imaginery way but involving kids in the making and playing with their own project. Great one to have ready for school holidays. Thanks for sharing.


  • What a great idea. Love the complexity that you can have. Great problem solving for the kids. Thanks for the idea


  • The grandkids had a great time with this and it doubled a s a second project with them decorating the outside of the toilet rolls. We actually used 12 toilet rolls and the kids had to work together. Thankyou, great idea


  • Such a great holiday craft project to keep the kids occupied!!! Love it! Thanks for the idea!

    • School holiday’s is creepy up great to use then


  • I like the idea of using a pompom. The kids don’t realise they are learning as they are having too much fun!


  • Another great STEM activity for young children. Problem solving and fun :)


  • Still a classic game and perfect for cold wet days.


  • Add a few more toilet rolls and I’m hoping this will keep my kids of all ages entertained while I prepare dinner or feed the baby!


  • This looks so cool. And not too difficult to set up. Great idea for those rainy days and school holidays


  • That’s a fun science project. I might try find different balls too… small bouncy ball. even a small ball of paper.


  • So cool, I’ve asked my children so many times if they would like me to buy them some marbles and every time they’ve answered “no”. Maybe this will change they’re minds. What a clever idea.


  • What a great idea! We go through so many toilet rolls so should be easy to stockpile some to try this out.
