Marble runs are like super fun rollercoasters for your marbles! Can you make the ride of your marble’s life? Time to take the Junk Marble Run Challenge!!
Junk Marble Run: The Build
Firstly you need to get together bits from your recycling. Toilet/kitchen roll holders are really great for making tunnels for your marbles to roll through. Cardboard boxes can be used to build structures and add height. Plastic bottles with their bottoms cut off also make good tubes and funnels. What other items can you find in the recycling that your marbles could roll through or off? . Get yourself a pile of recycling and collect as much as you can to make as long marble run as you can! Make sure you have some scissors and tape/glue to stick it all together.
Remember that your marble run needs to head downwards to pick up speed but we also want to make it exciting. How many twists, turns and ramps can you put in? What places in your home make natural ramps? Do you have some stairs? Or a chair or ladder you can slope things off of? Make sure if you are working in a team to hear everyone’s ideas. Below are some examples to take inspiration from. You may want to end your marble run with a cup or box for the marble to land in for its final stop, this will mean you need to line up the run to land your marble in the cup!
