Weird Science

It was the science fair last night. Alyssa and her friend Brianna put together a project and displayed it yesterday at school. They didn't win anything, which Alyssa was happy for. Last year she won and went to the district science fair and it was "boring". But they had a lot of fun doing their project. Their project was on invisible ink. They looked up different things that they could use as invisible ink. They used lemon juice and milk. They wrote messages on colored paper, photo paper, index cards, and computer paper. They discovered that the message could be seen best on the colored paper and the photo paper and when they used milk.
