It takes about 15 minutes or so. The water uses capillary action to move
water lower and lower in the hole. I have gone through a layer of shale or
limestone. It took a little longer, but you keep dropping the rod in the
hole...and the shale or limestone does shatter. I just keep a poking
motion going with the ground rod...bringing it up about a foot and then
stabbing it down the hole again. They use to dig wells using this same
action. Dropping a heavy lead ingot down the same hole....then hauling it
out...and dropping it again. They use water to moisten the hole. I think
the technique is good for 50 feet or so. If you have granite....good
luck...it isn't going to work.
