Hey resin,
   I can understand your reserve on this and it is well founded, but if you look at the laws, only melting a penny to profit off of the sale of the raw metal is against the law.  Since you are not selling the metal or creating a product in which you plan to sell with the metal in it, then you are legally in your rights.  Think about it,  have you ever gone to a fair or something and they have a penny crushing machine that takes your penny and smashes it flat and puts their logo on the penny?  Most everyone has.  That is not illegal because you are not planning to profit from what you are doing.  Now as you said, selling the metal of melted pennies is illegal, nowhere does it state that non-profit use is illegal.  But understand your concerns.

That sounds like a good idea.  Melting pennies would be easier that buying zinc, but I'm going to compare prices, you never know =P .  How would one remove the copper?  Is it all on top of the melted metal?

ammonium persulfate and with water and hydrogen peroxide to get rid of copper, however i have no idea what that would do to zinc

Actually the copper stays in chunks since the melting point of zinc is a lot lower than that of copper.  All you have to do is let all of the pennies melt and then scoop out the copper chunks with anything..You will probably need to stir the pennies once they start melting.  A spoon even works fine for it.  I would make sure it is not a spoon you want to use again.  I would also say that you do need to do this in a well ventilated area because I am not sure of the affects of vaporized zinc, but I have heard it can cause problems.  Just make sure you do not breathe in the fumes and that you do it in a well aired area and always uses good welding gloves or something of that sort when pouring.  No need in getting nasty burns if it hits your hands.  If you can do something to protect yourself from harm, DO IT.  Wear safety glasses and protect any exposed areas.  Unlike a lot of the other metals, Zinc will pour and mold very easily to anything that you want it to mold to without a lot splatter.  Make sure you are using dry pennies and where you pour it also dry.  Think of it this way, one roll of 50 pennies could make a very nice zinc rod for your experiment.  And like everything with the government, they only use the best.  So it will be a very pure grade of zinc.  The main thing to remember is common sense is the main ingredient of all experiments and if your shelf is empty of it, wait till you get some.  Without it, injury is sure to follow.

I don't know gentlemen, all that trouble, danger of burns from the hot metal, and fumes that could harm you doesn't seem much worth it when you can purchase zinc anodes on the internet from boatzincs.com. Why risk your health to save a few bucks, when you may end up injured and spend money on a doctor or hospital bill. Is it really worth the risk? Not to me anyway.

Please be careful everyone.
