Recently I posted something called The Boardrun. This got a little interest from the community.
Then it happened. I wondered if I could build up and away from the board instead of using sticks and rubber bands.
After a few experiments I now have this .. A marble run on stilt!
I'll go through you about how to use it here in the instructions.
A pegboard. It has to be done to fit your tips. Check out how to do one here.
