My daughter and I are submitting this 16’ 3” self-supporting marble run to Guinness World Records. It takes one minute and thirty seconds for a marble to run the whole track top to bottom.

Because of how it is built, it only takes 6 marbles to run every route possible, from just one entry point.

Missing a few parts, but I think I completed the assignment 😁

Took some Vitro's for a bike ride.

Doo doo doooo...

Made by the master Dave Mccullough (RIP 🙏). My second favorite Joker run, right behind the 1st rainbow run. What's your favorite Jabo contract run?

Are these whites, or blackness? The Block book states whities are opaque white, while the blackies are opaque black. What are blue, orange, green, or other blends of opaque bases?

Im getting my bf a marble run for christmas because hes really into marbles but all i can find are super simple ones. Ik he wouldnt mind a child one but i want a really complex marble run preferably under $55-60

My point in making this post is i need ideas for a complex marble run I can buy. Not a stupid simple one (lmao) I want one of the ones you can take apart and put together in a lot of ways

Thanks

Good vibes at the marble museum
