Peach is studying fossils in science. First she had to make a casting and then she was supposed to cover the casting in plaster of paris to make a mold. We didn't have any plaster of paris so I got out our book called
The Stuff that Fun is Made Of by Selena LaPorte and made up one of the concoctions in there. Well, it didn't work and we broke the casting yet too.
A new casting is now drying waiting for us to purchase some plaster of paris. Maybe next time it will work...
