Not long before I graduated, I climbed to the top of a parking garage near my dorm and did just that.
This was the highest place I could find on campus where I could safely drop the journal. It didn't do much in the way of aerial acrobatics, but it did hit the ground so hard that the spine split apart. Now the book is held together essentially by a piece of paper and some glue. Well, it's not called Keep This Journal In Perfect Condition, now, is it?
