  • The Boardrun - an Interchangeable Marble Run

    Very impressive, so simple and innovative. I am a grown up now. ;-) but I loved marble mazes when I was a kid. I work in STEM educational outreach and I am always on the lookout for quick and fun building projects using basic materials. The materials are so inexpensive, the kids could make it and then take it home. Brilliant! Thank you!
