Last night I planned to act out the Book of Mormon story of Samuel the Lamanite. I brought this to help us out:
The wall is made out of rice krispie treats, and all the people are pretzels and marshmellows. When we got to the part in the story where the people started throwing rocks, I let the girls throw marshmellows at Samuel. They were very careful and made sure that the "stones" didn't hit Samuel, just like it the story.
The whole thing only entertained them for 10 minutes, but oh well. It was fun anyway.
