These pesky, annoying little packets you get in pretty much everything from purses to boxed electronics are actually really handy to stockpile. Did you know Silica gel is a desiccant, a substance that absorbs moisture. Despite its misleading name, the silicate is actually a very porous mineral with a natural attraction to water molecules.
So, now I know this I will start to keep every single packet I find. These could be used to keep valuable papers, electronics, and ammo dry and moist free. I am sure there are loads of other uses too!
