We had just enough left to try again ~ using something considerably smaller.
The really sad part is that Ditz was far less enthused than I expected so it was a struggle to get her involved to start with. Art is, apparently, now considered *baby work*. *sigh*. It never did what a fresco is supposed to do because it hardened far too fast & I got shocked looks because I wanted proper plaster. In our instant society it seems the kids can't wait to paint their plaster models so we now have this super quick drying stuff & thwarted fresco~ists.
It was a far better science experiment. We had quite a discussion about why the plaster was heating up & how hot it would get before it hardened & cooled off but as an art exercise it was not a success. Win some, lose some I guess.
