I remember my first chemistry expiriment.
I made copper acetate when I was 9 wich was 5-6 years ago.
It was pretty easy just heat up a mixture of 50/50 White distilled vinegar, and hydrogen peroxide.
Once it's almost boiling add copper or pennys around the date i think its like 1960? because the new
pennys in america have very very little copper now. Then you just let the solution disolve the copper until it
turns blue or stop bubbling around the copper. Then just pour it into a container and you can do 3 things with it.
Boil it some more until it turns to power. Let it evaporate naturally and get crystals, or keep it as a liquid and
put metal in it to copper plate the metal.
