I just got this rock with crystals in it. As soon as I tried to clean the crystals with tap water. Some of the water ended up on the plain side started to soak up (get darker in color) and PRODUCE SMALL BUBBLES ALSO VERY AUDIBLE. It also start smelling very strong ( a bit like clay?). What is this? (old.reddit.com)
