Is it a penny? is it a dime? Is it an abomination? What hast chemistry created this time?
Using a solution of copper ions and a power supply, copper is electroplated onto the surface of a dime (made out of nickel).
This is a good example of a REDOX (reduction-oxidation) reaction, in which the copper ions gain electrons to be reduced to crystals of neutral copper metal.
The reaction is viewed under a dissecting microscope, with the time-lapse portions sped up by 100-200x.
