16 days agoThe cloth won’t fully seal the bottle, so liquid can fly out and splash from the cloth. If you don’t throw it properly or if you “fling” the rag you are going to set yourself or something nearby on fire and lob a non-flaming bottle. Storm matches burn for awhile, and you just need it to ignite when the bottle breaks, so you want to use a liquid with a low flash point and seal the bottle before chucking it.
And for sure don’t lob the bottle in an arc to your side instead of over your head so you don’t shower yourself in burning liquid. Or score the bottle along the base with a glass cutter/concrete if you are unsure whether the impact will shatter or not.
