Kraul Solar Airship
Solar-Powered Sky Explorer
Solar-Powered Sky Explorer
Watch the power of the sun take flight! This giant 3 by 1 metre solar airship soars skyward when sunlight warms the air inside its lightweight black plastic tube. As the air heats and becomes lighter than the surrounding air, the whole airship gently rises — a fascinating way to explore solar energy, air density, and lift. An inspiring hands-on experiment in renewable energy and atmospheric science.
Note: Must be used under direct adult supervision.
Founded by Mara Kraul in the 1920s, Kraul remains a family-owned company guided by Waldorf principles and a love for nature. Mara, her son Walter, and now grandson Christoph have shaped a timeless collection of experimental kits and educational outdoor toys, inspiring creativity, playful exploration and hands-on learning across generations.
Through play, children discover the wonders of the world around them — and with Kraul’s educational outdoor toys, they explore the magic of nature and technology through the four elements: earth, water, air, and fire. Whether they're building water wheels, launching air rockets, or crafting cable cars, hands-on play brings learning to life in the most joyful way.
Kraul toys encourage children to get outside, experiment freely, and experience natural forces first-hand. Along the way, they build essential skills like creativity, problem-solving, and scientific thinking — all while connecting deeply with the world they live in.
Made from local woods and sustainable materials, and crafted with care in Germany, Kraul’s toys not only nurture a child's love of learning, but also their respect for the environment they call home.
Kraul’s experimental kits offer children the chance to explore the fascinating world of science through hands-on learning. As young minds assemble construction kits, they gain a deeper understanding of technical connections and scientific principles. From magnets and electricity to aerodynamics, each kit opens a door to discovery, encouraging curiosity and problem-solving in an engaging way.
Through play, children develop important skills in mechanics, optics, and weather science. Kraul’s collections, designed with educational value in mind, empower children to experiment, explore, and discover how the world works—while fostering a love for science that can last a lifetime. These kits make complex concepts accessible and fun, transforming learning into an exciting adventure of exploration!
