Rated 2 out of 5 by from disappointing I bought this for my 12 year old daughter with great anticipation of a fun project for her. Couldn't be more disappointed! The instructions were somewhat unclear, the solution leaked through both the plaster and the mold (good thing I had something protecting the counter) and hardly any crystals formed. She had to paint the plaster when it was all done to make it even resemble a rock as it was completely red from the dye.
