Just a quick note about making capsules like this. For some reason the salts will slowly break down the casing. So keep that in mind they may only store for about a month of so until they are useless to use. I done a test years ago when I got my SN to see since I was thinking of the same idea and are now just going to make them when I need them. Not sure if it was the room temperature sped up the process of the breaking down or not.
