Fire brigade to the rescue - and no children's room would be complete without it. These three great models are ready to perform heroic rescues and save whole cities in the playroom. The kit includes an adapter for a standard PET bottle, which is built into the model and used as a water tank. It helps children learn the importance of sustainability, and it teaches them in a fun way that everyday objects have many different uses. An air pump creates pressure in the water-filled plastic bottle. When the valve is opened, the water shoots out of up to three nozzles from the connected fire hose. In this way, the children playfully learn the connection between air and water pressure.
