What will the cities of the future look like? How will people move around in these cities? How will they nourish themselves? How do futurists envision cities that float like islands on the oceans or orbit the Earth?

As our cities grow larger, the buildings also rise higher. The heroes Theo, Tess, and Quentin, known from WAS IST WAS-TV, visit New York, where they meet fearless construction workers. They are fascinated as they explore the tallest skyscraper in the world in Dubai and delve into the statics of these towering structures.

Manfred Baur, born on May 30 in the Allgäu region, aspired to reach great heights as a junior, dreaming of becoming an astronaut! He read WAS IST WAS books, gazed at the stars through a telescope, and eventually became a chemist, later a documentary filmmaker. As a father of a daughter and a son who always wanted to hear new stories from him, he gladly accepted the opportunity to travel with the WAS IST WAS characters Theo, Tess, and Quentin. Together, they ventured into Ancient Egypt, climbed the highest mountain in the world, and explored the deep sea - the adventures never run out. Sometimes, Manfred Baur also travels without the three, preferring destinations in Africa, by the sea, or to the lakes near Munich, where he currently lives.
