regenboog knikkerbaan geluiden cadeau set of 14 wooden ballsWatch and listen this marble run is a real sound experience. As soon as the marble at the top of the red wooden ball has stopped, it will roll down. The marble track will therefore play different tones from high to low. The sounds in combination with the rainbow colors make this marble track a real eye catcher. Roll different marbles. How will the sounds now sound in combination with each other?
