There are many marbling machines on the internet. Most of them are table top. Shawn Yeo, who founded VINCO, an educational company that specializes in creating environments that develop students to be independent learners, leaders and thinkers through tinkering approached me for this project.
Shawn explained the project to me enthusiastically. He wanted a marbling kit which could be attached to a whiteboard via a magnet. A marbling machine allows a marble to go through a set of obstacles, making a little noise in the process. They are also very interesting to watch.
The challenge of this project is the very very thin pieces. There are a lot of parts that are only 3mm thick.
