Tap Posted April 14, 2013 Share Posted April 14, 2013 i just ran across a white rock in my old supplies. i think it is the kind that you cover in liquid and it grows fluffy crystals. does this sound familiar to anyone? do u know what they are called. i wanted to let dd6 do it but i dont remember anything about it. what is the liquid used to activate it? vinegar maybe?
