Marble run course using pipe slopers, a large wooden funnel, a rain gutter, and iron balls

Описание: I made a satisfying DIY marble run course.
I created an original, handmade marble run course using pipe slopers, a large wooden funnel, and a rain gutter.
I used over 1,000 colorful balls.
I created it for ASMR with the sound of the balls rolling.
I hope you can view the entire creation process as a work of art.
Enjoy it as ASMR.
