A neat experiment you can do at home with off-the-shelf Muriatic acid.
Muriatic acid contains Hydrochloric acid, which reacts with the zinc inside a modern penny... More».
After the acid eats away all the zinc, all that's left is a copper shell only one thousandth of an inch thick!
You can use this penny shell for an old but simple magic trick where you hide a dime inside it. «LessNominate forDirectors Cut?Close

What has become of our money? Hmmm, a thin veneer of a monetary system, based on false promises and empty realities. Thanks Federal Reserve, for raping our Republic. Vote for Ron Paul, who will throw these bastards out and replace our currency with real copper pennies and not copper veneers. Great video!!!
no wonder u have 2 brush ur teeth after u through up, not only does ur breath smell but the hydrochloric acid in our stomachs would eat our mouths xP disgusting thought lol
cut all of ur pennies in half and let them sit, then melt done the copper into blocks, sell the blocks back the govt for even more more, cash out at back for pennies, repeta
You studied householding?
Kinda big to try to hold..
Sorry, me speaks englishe too low.
a small hole in the penny give you a hollow penny? The acid need only to contact the zinc?
But it would take a lot longer to work, of course.
so... how many drops do you put on your tongue? LOL
to make the tongue look like a shell...:)
I can see so many applications for this!
Hiding a microfilm anyone?
That's crazy.
What was yesterday's experiment?
Make sure you don't splash it in your eyes!
Pour wax in and make a mold to stamp my own pennies!
That stuff is strong! Imagine what it would do to your finger! Cool video dude!
Use baking soda (sodium bicarbonate) to neutralize the acid.
use sodium hydroxide
nice experiment! 5 stars

cool i like it but i live in australia is there something else i can use?
How did you figure this out?

I imagine instead of filing down one side, you scratch a small circle to expose zinc inside would also work?
