C-7 Foaming Explosive

C-7 Foaming Spray is a highly explosive compound that is used in demolitions by UNSC forces. It consists of various chemicals that react to a signal electrical current shock sent through a detonation switch. It is liquid in vacuum, but once contact with a hard surface and oxygen occurs, it becomes a foaming, semi-solid adhesive resin.Halo: First Strike, page 284
