Shape Charge

The Shape Charge is one of the first SGK made explosives, consisting of a block of Potassium Chlorate, a semi-spherical piece of steel and a shotgun shell. Created by Ben in Week 2 to save the SGK Base, it was used by Anthony to demolish a section rock blocking a hollow aquifer.

Principle of Working
The explosive itself uses the emptied shotgun shell acting as a blasting cap when a fuse (made of 9V batteries) is placed within and connected to the Potassium Chlorate. This was then placed into the concave face of the steel bowl, completing the charge.
