Inside there are no crystals, instead there are a pepsi bottle. I don't know how many years the bottle stayed in the thermal stream of "Puente del Inca" in Mendoza, Argentina, but I think no more than twenty. The sulphur and other minerals covered it. Isn't it nice?.
I am including a photo of the place where you may see an old thermal bathroom that was shaken by an earthquake, years ago.

Yes, I know. Thank you for your comment. See you.
I especially like the coke bottle fossil. You wouldn't think that much mineral would accumulate in the life of a coke bottle!
