Ok, today I decided to hook some metal discs (taken from a flywheel that was inside one of those "friction toys") to a 12v power source (DC of coarse).
I put the discs into a small container of Soda (Dr. Pepper, if you have to know).
Here is a diagram:

Ok now I have some phizzing at the negative charged disc.
After about an hour, I pullout the negative charged disc, and it is covered in this gross rust looking substance.
So can any tell me what is going on and if this is electroplating or something else, or just something I am not doing right. lol.
I am interesting on what is happining to the negativly charged disc.
The positively charged disc is also changing but not was drastic as the negative one. The discs are made of the same metal.
Oh and if anyone else tries to do this, don't drink the soda afterwords, it would probably taste really bad, and might be poisness too. I would also think that hydrogen is produced during this process, since the soda has water in it. So if the hydrogen is seperated from the water, oxgen is produced as well.
My theory is, that if this goes on for a long time, all the water in the soda will eventually be converted into oxgen and hydrogen. What would be interesting is, that all the other stuff in the soda (like the caffine and other ingredients) will be left behind. Of coarse, the metal discs probably won't last long enough for that to happen. So I would have to put new ones in every once in awhile.
