Best event by far!!! I'm just wondering for B, does ayone else not like the piece of paper? Anyway, about the chromotography, a good way to do it is do have 1 inch wide pieces of paper, about 4-5 inchs tall, and then put a small,light dot so that it is not touching the water but is close. Then, fold the top of the paper over the side of the beaker so the bottem of the paper is in the water, BUT THE DOT IS NOT!! Then wait and take them out once all of the colors look pure. Also, make sure to mark the top of the paper with a pencil so you know which is which.
