Dan's birthday and playing with baking soda

The boys were so excited about Dan's birthday. The loved the iced brownie (although very uncreative!).
The other day, I put some baking soda in a cookie sheet. The idea was that the boys would practice writing letters, etc. Isaiah wrote a letter or two, but they seemed happier just to play in it. Sam was hiding pennies and then finding them again. Isaiah was using the basting brush and making designs. It didn't quite serve the purpose I thought it would, but kids are very tactile, so it seemed to give them an outlet to experiment with a powder.
