Tut tut! Here comes a train as a puster pipe. The large chimney serves as a catching station for the lightweight polystyrene ball. The small wooden pipe transports the blown air through the chimney to the ball and it flies into the air as if by magic. It is important not to blow too hard or too weakly. The blowing ball is a great learning object, especially for small children to learn how to blow. 1 piece.
