Lucy participated in the Invention Fair this past week. Her invention was the Book-Bright, books that glow in the dark, so you don't need a book light and you can read all night.
When you looked in the box, there was a glowing page of a book that you could read. She created it by painting glow-in-the-dark paint onto the page. She tried a variety of glowing materials and this was the best.
