My guess is that what is happening is that the outer core water is evaporating.
I know this is because I saw not only water going up but bubbles inside of the water and in the tube from the outer core.
And then the water that we sprayed, due to density - is more dense then the dirt SO the water sank deeper into the crust, into the Moho
The Moho is the part of the crust that is between the upper crust and mantle.
