Solonite charge
From Battlestar Wiki, the free, open content Battlestar Galactica encyclopedia and episode guide
A solonite charge is a explosive device used in demolotions work. It is comprised of the destructive compound solonite, which apparently is in liquid or semi-liquid form, unlike a G-4 explosive.
A solonite charge has a detonator, timer, and light indicator. It is unknown how the charge attaches to an object. As seen during the application of such a device in "The Gun on Ice Planet Zero, Part II" charges are attached using some form of adhesive.
