Get out your crayons!!!

It's the Jefferson Lab Quark Coloring Book!!!
That's right boys and girls now you can color in the adventures of science's most exciting characters: Up, Down, Top, Bottom, Strange and Charm. I'm very excited.

p.s. Move over Mother Goose, these scientists have written the book like a nursery rhyme--the full poem is printed in the back. This is proof that science is better than poetry, is it too late to change my major again? Chemistry I miss you.
