ok

Suppose you are in a jail cell.
The cell is one layer of brick with mortar.
There is one window that is too high to reach (the window is barred).
You have one whole day (24 hrs.) till the townspeople are gonna kill you via burning at the stake.

you have:
a single carved out bench
a ceramic pitcher filled with water
a large loaf of spongey bread.

(if you think of bribing someone FORGET IT the entire town is against you)

so how do you get out?

(name the book it is from if you can)
don't just tell me the book
tell me how you think you could get out!
