This box (Marble Machine) produces silly sounds… Put a bering ball on the red chute, it rolls down a carrousel chute which swings the ball to one of the 15 holes leading to different items to produce the sounds. The items are a door bell (on the red door!), clock gong (the black spiral thing), nails, old bicycle spokes, springs and a wooden spiral track with click-clack sound.
Dimensions: 10 X 9 X 12 inch
Balls: steel bearing balls 1/2 inch diameter
Building time: 43 hours
