Step 11Other designs_3: The futuristic lemon battery
Similar design as the previous one.
The strange circular plastic item is a connector that you find in the box of light sticks ( 2 of them are included so you can make a sphere of light sticks)
We have 6 cells, every "cavity" contains a tiny piece of copper wire, a tiny piece of zinc wire, some lemon juice. The cavity is sealed with hot glue.
The cells are connected in series and a led is put in the center of the plastic connector. It already had a hole in the middle, perfect size for a led... here is how this battery started ;)
