Marble challenge guidance


What to
build with
The idea of making your own marble run is to be as creative as you like, using materials that you probably already have lying around in your recycling box. Basically, you want things that will make tunnels, chutes and towers.

I’d recommend:
• cardboard tubes (eg toilet rolls, or kitchen paper rolls – or even sturdier tubes from the inside of cling film rolls)

  • newspaper (to roll into tubes)
  • pipe lagging (foam insulation tubing)
  • cardboard boxes from eg cereal, tissues, toothpaste – or milk/juice cartons
  • plastic drinks bottles
  • egg cartons (to catch marbles at the end).
You have to bring:
  • One large cardboard box to
    build it all in
  • Scissors
  • Sellotape or masking tape
  • Double-sided tape
  • Sticky tac
• Marbles
Tips on making
your marble run
  • It’s easiest to build your marble run inside a big cardboard box with no lid. You can use tape or tac to hold different parts in place.
  • Cut cardboard tubes in half lengthways and tape them together end to end, forming a long chute.
  • You can use rolled up newspaper to form covered tunnels as well.
  • Cutting the top of a plastic drinks bottle off and turning it up-side-down makes a great funnel.
  • Other whole cardboard tubes or rolled up newspaper can serve as different height towers to rest your chutes on. Draw around the end of your chute see where to cut a semi-circle out of the tower, and slot your chute in. Then secure it with tape.
  • The top edge of your cardboard box is a good place to attach your first chute, giving your marble the helping hand of gravity. You could even make a little hole in the

side of the box to feed your marbles into, like the side of
a table football game.
  • Cut your egg carton into little cup shapes, which you
    can place at the end of your chutes for the marbles to drop into. Again, use tape or tac to keep them steady in your box.
  • If you’re up for a challenge, you could create alternative routes, by taping on a little cardboard tab that you can move into position to divert the marbles when required – a bit like points in a train track controlled by signals.
