Yep. Water is incompressible. The human body isn’t. Well, the part that isn’t water, that is.
We had a guy destroy a boulder about the size of a small garage by drill a hole in it, filling it with water, capping it, and setting off a charge about the size of a shotgun shell. Crumbled the majority of it, but isn’t that more hydrostatic shock or is that what we are talking about here?
