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.[1]
Uses[]
Its most notable use is when Corporal Locklear used it to destroy the Forerunner Crystal (the reason why the Covenant were chasing them), leading to his death.[2]
