Ah, the science fair. I was irrationally stressed out about Henry having to do a science fair project. Our evenings are busy enough that this science fair project was almost the really big straw that broke the camel's back. But, Henry finished it and worked really hard and got third place for the fourth grade. He was so proud. His teacher said he was really surprised and jumped up and down on his way to the stage to collect his ribbon. I really wish I could have seen that. He built different marshmallow guns and tested them to see which one would shoot the farthest. (The one with the longest barrel won.) As you will see from the pictures, the experiment was a family collaboration.
