Kraul’s ingenious Trout Boat is powered by the force of flowing water! At first, it floats away with the current, unwinding its string. But once the line is fully released, the boat comes to life — paddling steadily back against the current! A wonderful hands-on way for children to explore the power of water and motion.
Includes everything needed to get started, including a 10-meter string.

Discover Kraul Water Kits, Tools & Toys that turn streams and splashes into hands-on science and exploratory play.
Rooted in Waldorf principles and a family legacy since the 1920s, Kraul creates hands-on STEM kits that bring children closer to nature. Designed to explore water, air, earth, and fire, each build introduces real scientific ideas through playful experimentation. From moving mechanisms to outdoor-inspired constructions, every kit encourages meaningful discovery through doing.
Kraul invites children and families to build, test, and explore motion, gravity, and energy using thoughtfully crafted wooden kits made from natural materials. With a focus on learning through experience, these designs strengthen problem-solving, coordination, and curiosity while keeping play deeply connected to the natural world and real-life science exploration.
