A fire gimmick that is so flat that it will mount into any book, even a paperback!
Imagine fire from anything you want! Imagine what you can do with... MASTER FLASH
The Master Flash Gimmick is a very flat battery.
It has a nichrome wire loop for igniting flash cotton or flash paper.
It has a button for ignition. There is a double stick tape on the back to place the gimmick virtually anywhere.
Technically, you should be able to get fire from pretty much anything you want.
