Deep thoughts and some questions

It's like pounding on something with a 1" wood dowel rod, vs pounding on it with a 1" piece of steel Re-Bar. It still moves material at the end of the action.

Have done scuba diving, and every time you go down 30' that's another atmospheric pressure.

Have been down to 90' (3 atmospheres pressure) and the stilt still churns up the same as it does at 20' depth.

Too much of that silt churning up clouds up the visibility.

Like a 5 gallon bucket of thin mixed anti-freeze coolant that has sat for a week.
You try to pour the clean stuff off the top to save it, after a couple of tips with the bucket it's all clouded up again.
