What to do with "The Vice Busting Diet" Book

Okay, okay, so I have been ordering PGX Daily obviously. Lately, each bottle I have comes with a book. Julia Havey's - The Vice Busting Diet. I have given them away to friends and now I am not certain what to do with the rest.

I searched the internet and tried to come up with some ideas on what to do with these books:

1. Use them as weights for workouts.
2. Cut out the middle to hold my iPhone
3. Make a floating bookshelf? - I think this idea might work better with a hardcover
4. Turn it into a lamp
5. Turn it into a clock

Any other ideas?
