Harness the wind and watch it become real working power with the Kraul Sail Windmill Kit with Rainbow Sails.
Inspired by traditional Mediterranean windmills once used to pump water to fields, this impressive wooden construction kit turns one of nature’s invisible forces into movement you can actually see, follow and use.
The beautifully sewn rainbow sails catch the breeze and set the great wooden wheel in motion. Inside, a four gear transmission transfers that movement through the mechanism, allowing the windmill to do more than simply turn. It can be used to power compatible Kraul toys such as the Hammer Mill and carousel, showing how wind energy can be passed from one machine to another.
Building the windmill is a satisfying project in its own right. At approximately 80 cm, it becomes a substantial working model once complete, with the colourful sails bringing movement and life to a garden, balcony or outdoor learning space.
What makes it especially fascinating is the connection between past and present. For centuries, windmills converted moving air into useful mechanical work. Kraul brings that same principle into a beautifully visible form, so older children and adults can understand gears, transmission and wind power through something they have built themselves.
A wonderful project for capable young makers, home education and anyone fascinated by renewable energy, traditional engineering and the simple pleasure of seeing the wind put a machine to work.

Put the Wind to Work
The Sail Windmill becomes even more fascinating when its movement is used to power another Kraul mechanism.
Connect it to the Kraul Hammer Mill and watch the wind set the wooden hammers tapping, or use it to drive a Kraul Carousel. Kraul specifically designed the four gear transmission so that the windmill can power other toys in the range.
Kraul Toys & Experiment Kits
Kraul is a family run German toy maker creating wonderfully inventive toys and experiment kits that help children discover how nature and technology really work.
Inspired by the elements of Earth, Water, Air and Fire, Kraul toys encourage children to build, observe, experiment and find things out for themselves. From working windmills, cable cars and water wheels to optics, magnetism and mechanics, each design makes scientific ideas tangible through hands on discovery.
With roots in Waldorf education and a deep connection to the natural world, Kraul creates toys that invite children to experience an idea rather than simply being told how it works.
