OK, I am so STOKED right now it's unreal. I got the "fire in the bottle" settings right, my pictures are not grainy and I think they turned out SUH-WEET!!!
The trick seems to be that the room should not be completely dark, but have some ambient light. I think the shorter bottle also worked better (the rounder shaped one is a vinegar bottle with the label removed). I shook the alcohol around to coat the inside of the bottle and then let it sit with the top OPEN for about 15 seconds. Then, I just barely put the match over the top and it lit- WHOOSH! I think that it worked better if I used about 2 capfuls of alcohol instead of a lot too. Dang this was fun!!!!
