OUTLAW:
I remember reading an article where some university students built an Ark of the Covenant to scale.The sucker turned out to be an energy collector.Touch it,and it would blow you across the room..BOOM!!..Your a dead man!!..The only way it could be touched,was after you grounded it..I still have the book I`ll have to dig it out..Still unpacking my new place...OUTLAW.
Apparently it works like a Leyden Jar. See http://drzaius.ics.uci.edu/blogs/setbang/2006/06/the_ark_of_the_covenant.html
