Copper nails

We were learning how to transfer iron nails to copper. I enjoyed watching the copper transfer to the iron nails.

 Here is my explanation...

Have you ever wondered how copper transfers to iron nails? First we put salt and vinegar in a cup then we put the copper in the cup. Then we wait an hour then we pulled out the copper wire it started to rust then we put the copper wire in a cup. Then we put the iron nails in the cut the nail were absorbing the copper the next day the nails had turned into copper nails.
