Have You Ever...

In our place, security is intense. Guards are so into their job at all times. They'll grope every in of your body. You can't blame them for being strict, it's just part of their job. 

There is one flaw that I've noticed, they never check the insides of any book that you carry. Books that are thick and heavy.

This isn't even thick and heavy

Choose any thick book to carry such as Harry Potter, Calculus, or  maybe a Dictionary. Make sure that you can carry that book. Now cut a hole inside the book enough to make the desired object fit.  

any hole shape will do

Place the desired object inside the hole. Then try your luck and see if you can make your baggage unnoticed. Note that the book should be hand carried for it to be most effective.

If you tried doing this, tell me of what happened. Was it a success or were you apprehended?

You know that you can't do this in places that have x-ray scanners like airports, so don't even attempt to. This post is not intended to promote terrorism. Please don't try infiltrating firearms and explosives.
