"Organic," Economical, Weed Killer

Yesterday and today are big canning days. With canning comes pots of boiling water. When the canning is over, I take the pots outside and dump the steaming water on WEEDS. The weeds die. I figured this out by accident, but my mother-in-law told me that she does the same thing, so I guess it's a pretty effective means of eliminating weeds. :)
