A book is a snarf that goes up to peoples cars and spacks them with a pack of sponges. The pack pops and sponges fly all over the place and then people come back and say, "Why is my car covered in sponges?",. But in a life without people how long can they last?

1 day: The reverse effect. Books begin to track down bookshelves and fall onto the shelves. Just like teacups. Broken teacups gather themselves back together and jump back onto the table.

1 year: Sponges begin to decay along with this man. He explodes for unknown reasons.

5 years: All books have died of starvation.
