Скачать или смотреть Turn Pennies into a Battery - Free Power in a Crisis

Ever wondered how to power a light when the grid is down? In this quick DIY guide, RoachMacGyver shows how to turn household junk into a working battery. Using only a copper coin, a strip of cloth soaked in vinegar and a zinc screw, you’ll see how to assemble a simple electrochemical cell. Stacking these tiny cells increases voltage, and wiring the ends powers an LED, all without electricity or outlets.

You’ll learn step by step what materials you need (coins, screws, cloth, acid), how to prep the cloth and stack the layers, and how to connect wires to light an LED. Safety and practicality are front and centre: this project is for education and demonstration only, but it teaches the chemistry behind batteries and helps you appreciate off‑grid problem‑solving.

RoachMacGyver also explains why this technique matters in a post‑apocalyptic world, knowing how to repurpose waste into energy can be a life‑saving skill. If you enjoy survival science, prepping tips or quirky DIY experiments, this channel delivers bite‑sized lessons with a fun, hand‑drawn mascot.
