This marble run is a true sound experience! Once the glass marble is inserted into the red wooden ball, it starts to work its way from higher tones to lower tones of the lower part. Plus: the fresh, complementary rainbow colors make this acoustic marble run a decorative eye-catcher in the children's room!
Also perfect for experimenting and learning about sound. What will it sound like with a bunch of marbles at once? How does the space between the marbles change the sound effect? There is plenty of long-lasting entertainment guaranteed here!
Suitable from 3 years due to marbles
