There is some growth happening, I think. "Watch them grow right before our eyes!" My friend said jokingly as I placed the rocks in the tray at the beginning of the experiment. It has taken quite awhile, but it is actually obvious at this point that the crystals are growing and I really need to get a life.
I haven't measured them yet, but they seem to be protruding higher than before and close up they appear more "crystaly" and are starting some color changes.
I'm starting to wonder how many days it would take for the rocks to look like the picture? I'm also curious as to why all this is happening; what are these crystals made out of? Some research would be useful at this point. I'll see what I can find. Until next time, they grow on!!
