Marble Run? Ball Bearing track machine?

Question

I need to know the name of that thing that you see in science museums sometimes. The toys that are like it are called marble runs, but I'm looking for those cool things with tracks made of metal that have balls falling spinning and running around all over. Anyone know?

Answer 1

It sounds like you are referring to Rube Goldberg machines mechanical contraptions build based on timing, cause and effect...
