Kosmos Water Power

Water on the go. The snap-together parts create six cool models, all of which can be filled with water - and then it's off to the races. A long-distance shooting competition with the water gun, fun games with the sprinkler, as well as two cars and boats provide plenty of water play fun for children aged 8 to 12. The core of it all: the special air pressure pump, which serves as a unique rocket propulsion system for each model. But how do water power and compressed air work together? Exciting experiments will test the models. Have you figured out how many pumps are needed for the longest shot with the water gun? Be sure to note it down quickly in the detailed instructions. Whether in summer or in the bathtub - water is fun in every season.
