Experience the ingenuity of Leonardo Da Vinci with this functional 3D mechanical model of his Hydraulic Saw. Designed to demonstrate how an industrial hydraulic saw operates, this model uses a clever mechanism powered by water from a stream to move a log forward and cut it in half. Inspired by Da Vinci’s original sketches, the model offers an enjoyable and educational assembly experience, teaching STEM principles such as movement, force, and their applications in math and physics. The construction process is divided into smaller steps, allowing students to work in groups and reduce total assembly time. Once assembled, the model is fully functional and allows for experimentation with actual log cutting. This eco-friendly 3D STEM model is ideal for school or home customization. Made from sustainable wood, it requires no messy glue. Includes clear, colorful step-by-step assembly instructions. Built with sturdy construction and high-precision laser-cut plywood for amazing detail. Comes in an all-inclusive box for self-assembly.
