Anti-Gravity Book

The humor is a pun based on the double meaning of "put down." In one sense, it means to physically place a book down. In the other sense, it means to stop reading, implying that the book is so good that it is impossible to stop reading. The connection to anti-gravity makes it sound like the book is physically floating away because it cannot be put down due to its content.
