Re: [OT] RE: New 'electrical active' Armour to defeat hand held anti- tank rounds

Old Dawt Mill near where I grew up in the Ozarks.  There were pictures
made of the mill in which you can see a solid pebble that somehow
made it as an impurity into the glass.	These pictures are 80+
years old IIRC.  They still have the piece of glass, the pebble
has migrated down almost a foot (30cm) from it's original position.
