I've done this one:


Basically you get a glass jug and pour a bit of isopropyl alcohol (93%) or an equivalent in, slosh the alcohol all around to get a good bit of vapor in there, pour out the remaining alcohol and set the jug back down. Light a match and watch the pretty show.

Great one to do for your friends if they've been smoking a bit of weed.

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.

Same friend I just answered QOTW about
Did this with white spirit and several matches. Nothing happened, nothing happened, then it caught with a roaring jagged blue flame which took both his eyebrows off.

Good times.
