Take a metal powder, apply heat and pressure, and the metal powder forms something that's not quite metal, not quite a sponge.
Everything is different somehow, like everything has been turned slightly to the left, like something big is going to end soon. Portents of doom.
It's different than the normal post-show crash, deeper, more permanent.
The metal becomes porous to the point where liquids and gases can pass through, with rates depending on the density, on the porosity.
I don't know where I'm going, where this will all end up. It's gonna be a ride, and maybe not a fun one.
