Device: Library Bookmark Elevator

This device moves bookmarks between books on a tall reading pile. It is useful when your current book is on the third floor of the stack.

Step 1: Place one bookmark in the small elevator box. Do not place snacks inside. The elevator is serious about paper.

Step 2: Turn the side wheel slowly. If the elevator shakes, stop and apologize to the bookmark.

Step 3: When the bookmark reaches the correct book, slide it gently between the pages.

Warning: Do not use the elevator for pencils, keys, or tiny sandwiches. The library cannot be responsible for sandwich delays.

Storage: Keep the elevator beside the dictionary. It enjoys difficult words.
