The visitor enters the room and sees a label discussing how minerals may look different under different lights. They then can push a button or pull a string and the black light comes on. For you purposes, you can also add a glow-in-the-dark text panel that further explains fluorescence when the black light comes on. This may be the extent to which you can display these rocks with hands-on experience. Hope that helps. Lance Kita Exhibits Interpreter Bishop Museum [log in to unmask]
