Make a Battery with Coins | Science Experiment

Make a battery with pennies, nickels, salt, and vinegar in this fun science experiment! This type of battery is also called a voltaic pile. You can use a multimeter to measure the voltage and current produced by your battery, and even use it to light up an LED.
