hey. well, a fun, pretty easy, and interesting project to do is Which whitening toothpaste whitens the best? You can modify it to strips, etc, but that is the basic idea. You just have to get several different types of whitening toothpastes (preferably from diff brands) and then get pre-primered strips of wood (like the baseboard or frame kind of strips, the blocks don't work). Cut the strips into like 2 inch blocks. Then soak them in a mix of tea, coffee, and soda for at least 24 hours. Take them out if they are stained and let dry well. Then take the toothpastes and find which one takes the stain out best! And hey, good luck w/ the project!
