Marble run race ☆ TrixTrack wave slope & hand-cranked stairs. full table course 

Marble run with a TrixTrack course filled with bench tables in the park.
We created a long course using the familiar wave slope and hand-cranked stairs.
If you use hand-cranked stairs, you won't be able to roll many balls, so you will have to change the course midway through.
A beautiful ball flies into a glass bottle filled with water.
