His cold work explanation gives the impression that a density change is involved, but it’s really the ability of the particles (in his coffee example) to move past each other (called plastic slip in metals) that changes. Cold work creates dislocations (flaws in the crystal structure) that make plastic slip require more stress to occur, hence it hardens the material. If any thing these dislocations add open spaces in the material, but it’s not measurable as a density *decrease* until much more damage to the material has occurred than you would want for hardening purposes.
