You are located in a dark dungeon that has only one hole to the outside, so that air can be let in so you won’t die from suffocation.
This suits you just fine, as you were a former secret agent and have been subject to much harsher conditions.
An analysis of what is in the dungeon:
Cement walls, a bowling ball that can only be cracked that is glued fast to the ground, your wishlist from two years ago with the word hammer at the top. A mirror. A salt-shaker. And a pepper-shaker that only works if you reverse a superstition. A magical escape pad that works if you bombard it with tiny black particles.
One day, a gigantic guard comes into the room, shoves you aside and pushes a wad of fast-cementing glue into your life-hole (pun not intended). He leaves and slams the air-tight door shut and locks it.
How do you survive?
Note: There are many puns and play-on-words so don't think too literally
