i had rinsed my mouth out with sea salt and water and placed the rest of the water on a heater, forgot about it for days and came back to this on the bottom of the glass, if you look closely you'll see little Pyramids that were formed naturally. Makes me wonder about why and how the pyramids were really formed other than the popular story of it being a tomb made by thousands of people moving rocks across wet sand. I'm not suggesting they popped up out of knowhere but they have a natural quality and perhaps created by beings who knew something about how the universe works.
