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.
