My project is called Invisible Ink.  I learned something from my project.  I l  earned that if you mix lemon juice and water then put it on a regular piece of paper, then you let it dry.  When it is dry, you put it up to a light and it turns brown!  I also learned that it won't turn black because the original color is brown and you would have to put dye in the ink for it to turn black.  This is what you need for my project.   You would need to have half a piece of lemon, cotton swabs, original piece of paper and a place in your heart for fun.
