Sometime in November O Boy got into an "experiment" phase. An experiment usually ran like this: start with water, then start adding anything you can find on the craft shelf or in the kitchen and see what happens. In the "experiment" shown below that he did with Mr. T and the Little Sweetie I think the ingredients list included shaving cream, food coloring (Mr. T is adding) pepper, paper, glue, salt, peppermint extract, and possibly other things I didn't know about. One or two of these "experiments" he persuaded me to leave around for weeks to see what would happen to it (nothing much more than some evaporation). Now he's on to new things and I can breathe a sigh of relief.
