Water battery lights LED

Water battery lights LED

In my previous post I made a battery of nails, copper wire and vinegar. This time I used plain tap water (not salted or anything) and 12 bottle caps instead of 9 and guess what, the LED burns as brightly as with the vinegar!

If you want to make this battery, just follow the instructions on how to DIY a vinegar battery and change the vinegar for water.

    what if increase the size of the caps? (and temperature or types of nails?)

      Good question! Only increasing the size of the caps won’t help me getting more out of it. I have to increase the size of the nails as well. Not sure about temperature, haven’t really experimented with that. I did experiment with different types of metal. Voltage is always around .5 volt per cell, doesnt’t matter how large they are. It’s the amps you want in this case.
