What are some good things you can bring to the TAKS Testing?

We are having our Math and Reading tomorrow. I am wanting to know what are some good things I can bring. I don't want anything messy for snacks. So far, I have written down 2 books, 2 Sharpen Pencils, Water, Jacket, and that's all. Please give me some advice on some snacks and some resourceful things I can use. Thanks!
