MARBLE RUN CHALLENGE
MARBLE RUN CHALLENGE
It's been a tricky challenge - the homework task was to build a marble run that lasts longer than 25 seconds and is no bigger than an A3 footprint. All sorts of fancy designs were put forward involving funnels and loop the loops, but learning very quickly that that was a non-starter / fiendishly complicated, we have come up with this design - a classic marble run structure but with zig zag barriers along the way so as to slow down the transit of the marble...
Our top tip for this is to choose your glue wisely - pritt stick or school glue won't be strong enough, glue from a glue gun and wood adhesive glue worked well for us!
This is a list of the things we used:
1. Cardboard tubes (we got the ones we used from Hobbycraft). Wrapping paper tubes would also do the job.
2. A Glue Gun
3. Wood Adhesive : Amazon
4. Wooden lollipop sticks
5. Cardboard boxes (we used cling film and baking paper boxes cut in half)
6. Elastic
7. Wooden Coasters
8. Small piece of plywood
