Watch and listen - this marble run is a true sound experience!
As soon as a glass marble is inserted into the top of the wooden ball, it makes its way from the light tones to the darker tones in the lower leaves of this sound tree.
Plus: fresh, coordinated rainbow colours make the acoustic marble run a decorative eye-catcher in the nursery. By using different numbers of marbles, this shapely sound marble run can create exciting sound experiments: How do several balls sound at once, for example?
How does the spacing of the balls change the sound effect?
