In this example of electroplating I will show you how to electroplate nickles, quarters and dimes with the copper from pennies. Pleases read all the steps before starting.

Since I haven't found a nice instructable on electroplating, I am now making one.

Warning! This is my first instructable!

What you will need:
1-1.5 v power source (old batteries preferred)
some kind of battery holder with alligator clips
small, non-conductive, disposable container (plastic or glass, the small yogurt containers are great)
a weak acid (vinegar: acetic acid, or lemon/lime juice: citric acid)
two or more pennies
quarters, nickles and dimes (almost any hardware you want platted)
time (at least 1.5 hours...I think, 3 is better)
plastic wrap (Saran Wrap)

here is all the stuff I used, the 3000 sq ft platic wrap gets a picture of its own.

Step 1: Fill your container with the acid

First take you job, which will be a quarter for me, and mark its height inside the container - this will be a fill line.

Remove the quarter and fill the acid past the line. If you don't have enough acid, you can add water and dilute it, but do not go past 50% acid (since vinegar and juice is already diluted). I had only half the lime juice I need so I just added more water until the surface was past the fill line.
is there a way I could remove all the copper off of the penny, I just want the zinc.
<p>Zinc has a lower melting point than copper. If you just want to extract the zinc, you could melt the penny in a small expendable pan (a gas range should be sufficient). I probably killed many brain cells as a kid doing this with lead tire balances (free metal for my D&amp;D figure molds).</p>
do the first steps with the pennies for a really long time and the pennies should be copper free. Also I really like your sausage
<p>Copper wire or tubing might be better. Pennies are not really copper, and different years have different composition. 1983 to present is copper plated zinc.</p>
<p>Pre-83 pennies are still easy to find. It's interesting that the copper in these cents is worth more than the face value of the coins.</p>
<p>Since copper sulfate was readily available from drugstores when I was a kid, I copper plated anything I could experiment on, including the once-silver content coins which were still 'money.' (Now, every coin is a 'slug.')</p><p>I thought it was entertaining to have copper plated dines, quarters and half-dollars. </p><p>Also, although I havenot done any human 'trials' on babies, I have read and heard that a modern US penny can be fatal to a baby if swallowed. </p><p>The stomach acid breaks down the thin copper coating, and once the zinc core is exposed, the two metals will interact causing the creation of gas that will cause bloating and worst case, death. </p>
<p>nicely written up</p>
can i do gold or silver plating using simillar and untill green tint come we does not let the nickel to solution am i right
