It’s a big day at Sewanee Elementary School: the annual science fair, class pictures, and no telling what else! I got to “judge” the pre-school, kindergarten, and first grade projects. This one was terrific: can you really use toothpaste as glue? The answer: yes! It works great for gluing plastic, cardboard, and paper. “Could you build a house with it?” “”Nooo!!!” “How could you change this experiment to learn even more?” “I might try my baby sister’s baby toothpaste.” Great idea! Way to go SES — I hope the children enjoyed it half as much as I did.
