Kraul Spielzeug
Kraul is a German family business that encourages a love of nature, observation, and experimentation. Using the basic elements around us (earth, fire, wind, and water), Kraul's STEAM and engineering science kids allow kids to wonder at the world and inspire hours of nature based play.
A fascinating and decorative weather glass for your desk or window sill. It is quickly assembled and then reliably shows all changes in air pressure, because the change in the water level is controlled by the air pressure.
