I don't know about adding alcohol as a preservative, simply because it doesn't seem necessary. But the general idea sounds promising. Like others have said, be careful about soaking certain crystals in water or alcohol, for both your sake and that of the crystal. Also, I agree about water itself having crystalline properties. And sal****er could possibly also be considered a crystal elixer. :)
....Is s-a-l-t-w-a-t-e-r censored? Like freshwater and sal****er? Ohhh, I see what happened....Haha....
