Requirements: A great attitude! You certainly can’t be precious about your walls for this one! You will need: small balls such as marbles, tubes (toilet paper, foil, wrapping paper), train track pieces, masking tape, funnels, boxes, containers, a bell (if you like to end with a bang!).
- Start from the top and using the tape, fix the pieces of ball run components you have collected to the wall.
- Repeat in sections, changing direction, until the ball run makes it to the bottom of the wall.
- Place a bell in the final container for the ball to hit as it finishes the circuit.
