Make a Battery with Coins | Science Experiment

This video tutorial demonstrates how to create a simple battery using coins, known as a voltaic pile. It covers the materials needed, including pennies, nickels, a multimeter, and an LED. The video guides viewers through building a single cell and stacking multiple cells to form a voltaic pile. It explains how to measure voltage and troubleshoot common issues, such as pressure and electrolyte levels. The tutorial also shows how to test the battery's current using an LED, highlighting that the battery may not produce enough current for full brightness. The video concludes with tips for successful experimentation.
