EXPERIMENT - How to make a battery!  

Hello this is Minus and you are watching how and why.
Every week (well sort of) I upload videos about science, history and general knowledge.
You can build your own battery out of salt, water, a few coins and washers! IT was the first battery every made, that could continuously provide an electric current to a circuit. As Alessandro Volta did in 1799 I made a voltaic pile using the same materials. And it is perfectly safe as the voltage is so low, it isn't harmful to you! You can do it by yourself following the steps you see in the video you will be able to make it too!
The more subs you guys make, the more videos mean for me. It motivates me make new and better videos so a sub to my channel would be hugely appreciated!
