We created an original marble run course using handmade wooden slopes and bricks and blocks.
Place a large number of colored wooden balls and billiard balls into a 4 meter transparent pipe and roll them. Make a dam with bricks to collect balls.
When the dam is opened, the collected balls roll into the water.
The sound of rolling balls and water sounds is soothing and it's ASMR.
