Building a battery from scratch is an interesting project. The two 'classic' chemistry-lab batteries are:
- the Daniell Cell (uses copper and zinc electrodes in sulfuric acid). Extremely messy and only makes 1 volt.
- the LeClanche Cell (the classic "dry cell" flashlight battery). A more-intuitive build project, and makes several volts by hooking in series. We can build and compare 2 variations using Zn and Mg for the anodes.
