Making your own coke can battery is often seen as extremely unnecessary and not at all cost effective, simply because of the availability of energy storage technologies on the market.
But if you have some spare soda cans, and want to turn them into power generators, here is the coolest and most simple tutorial.
Materials and Tools
All you need to make the simplest coke can battery is:
- 1 cola can
- 1 copper coin
- 1 can opener
- 1 glass or a cup
- Crocodile clips
- Wire wool
- Metal stick, screwdriver, spade or an electric drill
In case you would like to give the set-up a boost, and be able to produce enough power to light up a small LED, you will need 6 times the above mentioned materials (except for the can opener), and table salt. And for even more power, you will need some standard commercially sold drain cleaner.
