The pro move it to get some phosphorus and drop it inside the bottle. The phosphorus auto ignites once the bottle is broken and it’s exposed to air. No messing with open flame, just throw and wait for your federal indictment for building firebombs.

Failing that, use a storm match instead of rag. Much easier to handle and less likely to snuff out.
