melting a crystal of nails
Loading...
Uploaded by smorris123 on Sep 15, 2010
A perfectly ordered array of nails is arranged on a horizontal, flat rectangular plate. Then the plate is shaken vertically at 37Hz with a slowing increasing amplitude of acceleration. In this stop action movie, we see the initially ordered "crystal" melt into a layered smectic phase, with ever more defects, and then into a nematic and eventually into a totally disordered "liquid" phase.
The nails are made of brass (so as to be non-magnetic). They are 1 inch long.

why do they have to be non-magnetic?

@pcdsgh Because the shaker we are using has a powerful permanent magnet in it. If the nails get magnetized, they all clump together.
