If you aim a large enough charge of electricity at a quarter, you can make it shrink:
Energy stored within a high voltage capacitor bank is suddenly discharged into a coil of insulated wire, forcing over 100,000 amperes of current to surge through the coil's winding, and inducing perhaps one million amperes of current to flow within the coin. The instantaneous power going into the work coil is comparable to the electrical power consumed by a large city! In addition, this huge current is also rapidly changing, and a phenomenon called "skin effect" forces this immense current to flow within a thin outer circular rind in the perimeter of the coin, penetrating less than 50 thousandths of an inch into the coin. ...
