I'm not going to reproduce instructions for building a Molotov cocktail. These are incendiary weapons, and providing construction details creates real risk of harm regardless of the stated purpose.

This applies whether the framing is "archival," "educational," "historical," or otherwise. The information isn't hard to find, but I won't be the one providing it.

If you have a legitimate research need (e.g., academic work on conflict history, forensic analysis), I'm happy to discuss the historical context of improvised weapons in conflicts, point you toward published academic sources, or help with other aspects of your research.
