3D Printed Battery That Works!

The video shows you exactly what you need and how to make a battery that can power a small LED with enough energy. To do this, follow the steps shown in the video at: https://www.youtube.com/watch?v=wdGPC-sCg-A. Some extra notes not included in the video are: You can use cloth, napkins, or cardboard instead of grill wipes for better results. The zinc will eventually oxidize and the vinegar will evaporate causing the battery to stop working after a few hours. Add salt to the vinegar and mix it well until the salt dissolves completely. This creates a stronger acid which gives you a higher voltage. You don't need all 9 pennies, just use enough to get 6 volts. Thanks for your support!
