Giovanni the Fox usually invents using his wife Julia’s kitchen tools. Of course, Julia does not like it much because there is always some important pot or potato masher that has gone missing. One day Giovanni was inventing behind the kitchen table so intensely that sweat pearls started gleaming on his forehead, but the invention simply did not turn on. Fortunately, Lotte walked by, recognised uncle Giovanni’s problem and gave him some good advice: “Uncle Giovanni, use a sieve!” Giovanni put a sieve into his invention and the fountain was promptly finished! The fountain is a valuable invention because it is fun to watch the water play, and on Saturday evenings it also dispenses carrot lemonade.
