Molecular foam (Earth-8765)

Molecular foam is an experimental and unstable foam capable of shattering through any piece, including metal, concrete, and, as its name implies, molecules.

History
Molecular foam was used by Owen Davian's mercenaries at the Chesapeake Bay Bridge-Tunnel to rescue him from CIA custody. By spraying it on armored car, the vehicle's lateral was completely destroyed, allowing Davian to escape.
