Automatic Soap Dispenser Science Project STEM DIY Working Model Kit is an engaging educational experiment designed to help students understand basic electronics, pump mechanisms, and automation technology. This hands-on STEM kit allows students to build a touch-free liquid dispensing system using a mini water pump, tube, circuit, and nozzle. When powered by a battery, the pump pushes liquid through the tube and automatically dispenses it, demonstrating real-life hygiene technology and engineering concepts. This DIY working model is ideal for school science exhibitions, STEM learning activities, and classroom demonstrations. It encourages creativity, problem-solving, and practical learning while helping students explore concepts such as liquid flow, basic circuitry, and mechanical operation. The project is easy to assemble and perfect for students of Class 6–12 who want to create an innovative science experiment. Perfect for science fairs, STEM education, and DIY electronics learning, this project helps students gain hands-on experience while building a functional automatic soap dispenser model.
