make your own graphene at home?

i heard that you can make graphene at home by putting graphite oxide on dvd and then use a dvd burner to create patterns in your dvd burner....
is that true? if it is true i would really like to try to make some at home; and bow much is graphite oxide anyways.... and why is graphene so expensive, $125 to 25g of graphene; i mean you can make it from pencil, paper, and sticky tape, how much is that?
anyways... here is my question:
can i really make graphene at home? or is it still in the labs only? and can a regular person afford graphite oxides?
i heard that graphene is only water permissible, so if i can make graphene at home, maybe i can make a filter for my cup if i only wanted to drink pure water
