Oh, how I wish I had my camera at school with me yesterday for the first class using my super homemade Play Dough. So instead, you'll all have to use the power of your imaginations. All 7 of you reading this. (I installed a counter the other day--check out my staggering stats!)
My charming 2nd graders were the first to experience the green dough. I explained what we were doing with it, and gave them each a small ball of dough. It seemed a little less...firm...than when I put it in the fridge (as instructed) the night before. In my early morning grogginess ("groggy head" as my Dad used to call it) I thought, hey--they just need to work with the dough and it will firm up again.
What I quickly had on my hands was a class of 7 year olds who were surprisingly upset to be covered in green mush.
Amid cries of "Don't touch ANYTHING" and "Line up QUIETLY" I got them to the bathrooms, and with my Principal's help (who of course, was walking through the hall at just that moment--thankfully he's a kind, sympathetic, humorous man!) we got them cleaned up in time to go back to class.
Needless to say, the lesson with the Play Dough was altered to subsequent classes.
The moral of the story? Make sure the Play Dough has completely cooled before you put in in a sealed container in the fridge. Condensation can be a real drag.
