Item 485 is a green hardback book titled "The Three States of Antimatter", written by Ann T. Mattur. when the book is opened, there are no words on the page. However, when opened, a liquid, solid, or gas will emerge. Through testing we have found these items to be antimatter, rendering it extremely dangerous if exposed to the original matter. The book is not to be opened at any time due to this.
