That is pretty cool
What happens if you don't pour the alcohol out before you light it?

Fancy candle or explosion.

Nothing, really.
The limiting factor on the fire is the supply of oxygen. It just sits there.

I just pour out the excess because it's neater when you recharge the air inside (I usually just blow into it, or maybe insert a straw into the bottle and blow through that). The benefit is that the next time the glass is already warm, so the alcohol vaporizes easier.

You can do this with a wine bottle, I might add.

Awesome
Your comment about the glass. Wing warm second time round reminded me of my dad rolling a nearly empty bottle of metaxa to vapourise it then doing the same thing. Seem to remember it whisteling :-)

You have a potential to make
ketones, aldehydes, monoxide? My A-level chemistry is a bit fuzzy. All a good recipe for a headache anyway.
