Lighter fluid (naptha) and flash point review;
The flash point for lighter fluid is (depending on humidity) between 104F and 140F.
This is why when you go to light your ambient temperature charcoal in the weber grill, after soaking the charcoal in lighter fluid, you have to hold the match there for a few seconds before it ignites. Even in the summer, if you just toss a match on to it, the match will often go out before the naptha ignites. The flame from the match must raise the surface temperature of the naptha before the naptha will ignites.
Conversely, once you get it going, even just a little bit, and you add additional lighter fluid...poof! it ignites instantly!
I don't believe that at 1:00am in Dallas, it would be hot enough outside to make it possible to squirt naptha on someone, throw a lighter (which would not just stick to them..it would deflect or "bounce" off, having only stayed in contact for a fraction of a second) and cause it to ignite.
Damn, we got some smart dudes on this sight. Nice.
