Here are some additional marble run challenges to try or elements to add: – Include a set amount of turns the marble must make before it reaches the finish line. – Create a tunnel or other feature the marble must travel through. – Build a ramp for the marble to go up and back down again.
Add a piece, remove a piece, you might find a corner too tight for the marble to roll through, so you will need to rethink the design and change it around!
It can become a really cool problem-solving activity. You could make just one path that will work to get to the finish, or you can make several!
