At atmospheric pressure, the carbon dioxide gas escapes very slowly from the supersaturated liquid.

As more and more of these platinum atoms form, the solution quickly becomes supersaturated and platinum starts to precipitate in the form of sub nanometre particles.

And over the tops of them is 3,000 to 4,000 meters of water creating enormous pressure, forcing water down through the cracks toward the center of the earth, until it hits a magma chamber where it becomes superheated and supersaturated with minerals, reverses its flow and starts shooting back to the surface and is ejected out of the earth like a geyser at Yellowstone.
