Shrunken Quarters

Well here's the shrunken quarter.  Actually we did quite a few coins.  Basically I was working a creating a test bed which simulates lightning strikes on buried cable in sand.  Now I can't say where said cable would be.  Anyway a coworker had read about shrinking coins and he realize I had recreated the same setup for this cable test.  First attempt resulted in shattering a piece of 1/2 inch lexan and shrapnel in my ear!  There are still holes in the ceiling and wall. We later used a flack jacket buried in sand to contain the sharpnel.  Each time we make a coil of #14 wire (same stuff that feed your house outlets) and connect it to large capacitors fed with 30,000 volts. The quarter is in the middle of the coil.  The coil is destroyed and the quarter is strunk.

    Holy crap, that is really incredible!
    Ok..this might be a dumb question…but ….how does the quarter shrink? Is there actual….um…molecular "shrinkage"?

    There is no molecular shrinkage. The coins become thicker and I assume ever so slightly denser.
