Step 3: Assemble and start plating!
step1 - connect the copper electrode to the positive side of the battery, and dip it in the copper sulphate sollution(copper sulphate crystals dissolved in water).
step2 - connect the carbon electrode to the negetive end of the battery and dip it in the sollution too.
step3 - drop the metal object you want to plate into the sollution.
edit: as pointed out by @HeWantsRevenge in the comments- for a nice even coating, it might be a good idea to suspend the object.. with thread or wire.
