The ENGINO® Discovering STEM™ Fluid Dynamics Set (E83.1) transforms core physics concepts into exciting, practical discoveries.
Through interactive model building and experiments, students learn how fluids behave in motion and at rest- studying the science behind hydraulics, buoyancy, flow, air pressure, and propulsion.

Learners can build 6 functional models, including a hydraulic platform, submarine, siphon device, hydrostatic tower, communicating vessels, and water jet launcher.
Each activity is supported by detailed theory and hands-on experiments that demonstrate real-world principles such as pressure difference, density, and force transmission.

With 273 precision-molded Engino® parts, a syringe-and-tubing system, and an illustrated theory booklet, students can investigate how engineers apply these concepts in ships, airplanes, and hydraulic machines.

The set integrates building, learning, and testing- bridging science, engineering, and design thinking for the next generation of innovators.

Andrew C. ★★★★★

Built the hydraulic lift model with my son last weekend - the instructions were clear and he loved seeing the pistons move with real water pressure.

Jacob ★★★★★

Bought this for my 11-year-old who usually zones out during science talk, but the syringe-and-tube experiments actually got him explaining water pressure to me at dinner. We started with the hydraulic arm model first and it worked on the first try.

Mia ★★★★★

Bought this for my 10-year-old who's obsessed with how things work, and the hydraulic models kept him busy for a whole rainy weekend. The instructions actually explain the physics behind each build instead of just showing pictures, which I appreciated. Six models means it didn't get boring after the
