Discover the power of physics with iM.Master’s Hydraulic Series – where hands-on engineering meets creative design! Our hydraulic building kits simulate real-world machinery through manual hydraulic systems, enabling kids and adults to construct cranes, excavators, and more with lever-controlled fluid dynamics. No batteries required – these models use piston-driven mechanics for lifelike lifting, rotating, and digging actions. Perfect for STEM learners aged 10+, the kits teach fluid pressure principles, mechanical advantage, and problem-solving through interactive play. With multi-functional joints and modular designs, builders can create dynamic structures while mastering hydraulic fundamentals. Ideal for classrooms or home labs, these kits bridge play and science, turning abstract concepts into tangible, kinetic adventures.
