Marble run race ☆ Wooden handmade slope u0026 transparent long pipe Billiard ball Colorful ball
We built an original marble run course using colorful DIY wooden slopes. The transparent pipe is 4 meters long, and balls are poured into it and rolled. It's very impressive.
We ran two trucks at a time in a race.
I'm very interested to see which truck runs faster.
The sound of water and beads is very soothing.
