Watch and listen – this marble run is a real 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 colors make the acoustic marble run a decorative eye-catcher in the children’s room! Children love to experiment! By using different numbers of marbles, exciting sound experiments can be created with this shapely sound marble run: How do several marbles sound at once, for example? How does the spacing of the balls change the sound effect? Long-term employment is guaranteed here!
