This is a type of marble run designed and made by Yukari. Steel balls roll down boards shaped like leaves, creating beautiful sounds as they go. When many balls are rolled at once, it feels as if you are listening to an endless scale. By watching the video, you can clearly see how the balls roll and how the sounds gradually change.

This project began when Yukari found leftover regular pentagonal prism rods in the workshop. Angled notches were cut into the rods, and various leaf shapes were 3D printed and attached for testing. Through this process, the final design was achieved with a size that produces beautiful sounds and allows the balls to roll smoothly.

A stick with an embedded magnet is included to make it easy to pick up the balls collected in the tray at the bottom.

Even small children can play with this, but since it comes with small balls, please be careful to prevent any accidents such as swallowing.
