C-7 Foaming Explosive

is a UNSC explosive device designed for demolitions. C-7 exists as a liquid when contained inside a pressurised vacuum, but once it contacts with oxygen it turns into a semi-solid explosive. 
==Uses==
Composition-7 foaming Explosive is often used for more delicate operations, such as breaching, using the explosive to cut through a wall or door, opening hardened equipment with minute, controlled explosive or controlled ordnance detonation. However, in enough amounts, the explosive can be used for serious destruction, allowing it to be injected into cracks inside structures or armour, or rigged up as crude time bombs. 
==Operation==
The C-7 is contained inside a sealed titanium allow can, with an folding nozzle. This allows it to be accurately inserted. Its got a screw lock pressure cap, allowing the flow of the C-7 to be modified by the operator. Each can carries 400ml of explosive.
