DIY Automatic Water Dispenser Machine Working Model | Easy STEM Science Project

Learn how to make a fully functional DIY Automatic Water Dispenser Machine using cardboard and a mini DC water pump! This easy-to-follow, step-by-step tutorial is perfect for school science exhibitions, middle or high school STEM projects, or just a fun weekend engineering project at home. In this video, we use easily available materials to construct a working water dispenser prototype. We will assemble the cardboard chassis, wire a 3.7V rechargeable battery to a mini submersible DC motor pump, and build a neat touch-free or switch-activated dispensing loop. This is an excellent way for students to explore basic circuitry, fluid dynamics, and green engineering concepts! 📦 MATERIALS & COMPONENTS USED: • Cardboard (Recycled shipping boxes) • Plastic Jar • Mini DC Water Pump (3V - 5V Submersible) • 3.7V Rechargeable Li-ion Battery & Battery Holder • Clear Vinyl Tubing / Level Pipe • Razor Blade (for Push Button Switch) • Old Pen • Hot Glue Gun & Utility Knife • Connecting Wires If you found this school science project helpful, please give this video a thumbs up, leave a comment below with your project ideas, and SUBSCRIBE for more fun DIY engineering and science experiments! #ScienceProject #DIYWaterDispenser #CardboardCraft #STEMProjects #SchoolScienceExhibition #HowToMake #DCPumpProject #InventionIdeas #CreativeFest
