Grounding with a Earth box?


OK so help be understand something.   I understand the value of grounding equipment, but what is the value of having a woodbox with salt, earth, minerals etc  do for grounding?  How is supposed to work or be better?

brubin,

The OCD guy gave you the recipe, why not build it and report your impressions? 
You're missing my point.  This is not one guy making a box -  its an item sold by retailers.   My question is how does work and is better than true ground?  Otherwise, why is ay one doing it?
I put cat litter in a beer can with a wire and it works.

I can gear the difference...

some of this stuff is crazy ass snake oil.
