Master the Hydraulic Principles Used in Modern Industry

This DIY kit faithfully replicates the operation of professional cranes and excavators. By operating the four control syringes, water flows through transparent tubes to transmit hydraulic pressure to each joint of the arm. This tangible demonstration of the Pascal’s Law allows for the grasping, lifting, and moving of small objects with surprising precision. Each movement illustrates how the force of an incompressible liquid transforms into amplified mechanical power, just like in construction machinery.

Educational Carpentry Developing Patience and Advanced Technical Skills

Made of untreated natural wood, this model offers a warm aesthetic and exceptional durability. The pre-cut and pre-drilled pieces fit together precisely, guided by a detailed illustrated manual. Assembly encourages manual dexterity and spatial understanding through progressive mechanical challenges. Ideal for school science projects or collaborative family activities, this arm can operate in solo mode with integrated support or as a team, with each person controlling a syringe to coordinate complex movements.
