So, where can I get some graphite oxide? This looks easier than 3D printing.

There is some interesting information about graphite oxide in Wikipedia (I didn't know the compound) http://en.wikipedia.org/wiki/Graphite_oxide http://en.wikipedia.org/wiki/Graphite_oxide After a little googling I found a store: https://graphene-supermarket.com/Graphene_Oxide/Solutions/ https://graphene-supermarket.com/Graphene_Oxide/Solutions/ (I'm not affiliated with them. I don't ever know them. Verify they are legit.) I didn't find any strong warning about graphite oxide, but I don't know the compound. If you decide to use it find someone with experience in the laboratory, be careful and RTFSL.

  Just a guess- and I could be completely wrong on this, but graphite spray that you use for locks (also has alcohol or some other quick-evaporating liquid in it) might do the trick. I'm going to mess with this some today. Will report back results. I wonder how long you have to "cook" it with the laser for? I'm also imagining that I'll want to flip the DVD drive upside down so I can keep the liquid mostly in place. Wondering how the spinning will effect it as well. This is going to be a hell of a messy experiment. About a year ago I heard how good of a filter for water graphene is, so I bought graphenewater.com. If this is an easier way to make large amounts of graphene, I just might have to put this to use.

    They used a lightscribe dvd burner. I am not sure if the laser is much different, but it scribes the "back" side of a dvd. http://cleantechnica.com/2012/03/17/make-your-own-supercapacitor-with-an-ordinary-dvd/ http://cleantechnica.com/2012/03/17/make-your-own-supercapac...

Hum I guess that the easiest way is to use an electrolytic cell, http://en.wikipedia.org/wiki/Electrolytic_cell http://en.wikipedia.org/wiki/Electrolytic_cell and put graphite (the black thing inside your pencile) to both electrodes... Put an acid solution water and ammoniac will be fine... I am trying right now... The water is getting less limpid and gasses (I guess O2 and H2) are coming out. I am using a 9 Volts battery.

  Tell me more about this! I'm no chemistry major but I'm wondering how it went?

    I get graphite oxide in an solution (read + water), I put the solution in a normal cd, I wait so it get dry then I put it in a ligthscribe burner. And I am stucked, the burner don't want to burn my cd, obviously. I need something to force it to write...
