What was used for the separator between the 2 half cells?

[nitrozil]

@domkixarse

The separator is a 1mm gypsum sheet.

[nitrozil]

Zinc-Sulfate= Zinc (gutter)+ sulfuric acid (gas station)

You can buy Copper-sulfate (agriculture).

Cool. Is There Any Liquid In The TicTac Containers? If So What Is It? and how do you recharge it? Like a Normal Battery?

[nitrozil]

Yes, There is zinc-sulfate and copeer-sulfate water solution in this battery.

Charge: pc power supply 5V 1h with 1A.

[nitrozil]

Zinc-sulfat and Copper-sulfate

Pretty cool. How long did this battery remain useable/chargeable? Thanks

Lovely piece of work. A great use of the Tic Tac box. Always felt it was over the top for a range of sweets !

The point is that mp3 players are amazing things. if we would use them to play files rather than a lap top you can save a lot of energy.

@6341026p Couldn't make it work properly with gypsm (only a small amount of current could be drawn)... couldn't get anywhere near as much current as nitrozil. But I did manage to make a non-rechargeable cell that works very well if your interested.
