When the marble leaves the loop d' loop, the track is above it and it has a counter-clockwise spin. After it leaves the loop the track is below it and it would need to change it's rotation to clockwise. The spin on the marble is what slows it.
@motleymdg That's freakin' genius - I had to watch like 4x before I realized that. I just got the itch to build a rolling ball sculpture clock - but I've never bent metal or TIG welded or anything. The only reference I have is a model I have from the 80s and a giant version at the science museum down here. Time for a crash course.
This is all trial and error, but it is built in my head just before I go and actually bend the wire. I don't make any plans. I use 1/8" stainless steel wire, TIG welded.
How about you show us some stuff how you actually make these kinds of things? What do you use material wise, and it this all built in a trial&error fashion, or are you really designing all the curves and slides? End results: bd (both thumbs up, bd is an acronym to "beide duimen" in dutch)
Its actually quite simple if you understand. You are very creative man!

How did you get it to brake so fast?
