Offhand, I can think of a few dozen. It is a federal offense to disclose the exact chemicals and processes required. NEVER take Mentho's and Diet Coke on an airliner. Ever. There is no need for Draino crystals, aluminum, an unnamed catalyst, and an ignition source on any aircraft, ever.
Menthos and diet coke would make quite a mess, but no downed plane.
Menthols? and Diet Coke? Why?
