Kosmos Water Power

Water on! From the snap-together pieces, six cool models are created, 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 that 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 it takes for the longest shot with the water gun? Quickly jot it down in the detailed instructions. Whether in summer or in the bathtub - water is fun all year round.
