[MEGA Vortex Funnel Marble Run (part 1, 1200 rainbow marbles) ASMR] (Viewer #188,368)

The first segment starts out at 50% speed, and I find it beautiful and soothing. The second segment is full speed, and it’s just not as nice. Toward the end, the glow-in-the-dark marbles are interesting since you can only see moving lights and have no idea why they’re moving the way they are.
