(Don't) Make Your Own Fire Tornado 86 86

Flash Modin writes "In the last two weeks, both water and fire tornadoes have been widely covered by the media. As any physicists would have, we immediately thought 'I want to do that!' SO... You should absolutely, under no circumstances, not attempt to recreate the following fire tornado; but if you did, here's exactly what you would need, how you would do it, and what it would look like."

    Ah yes... I seem to remember this particular method resulting in second degree burns on two of my friends when the fire flashed back to the bottle of lighter fluid and exploded.

    Not recommended. Steady streams of flammable liquid connecting flame to a fuel bottle is a stupid idea.

    No, you are making that up. Lighter fluid isn't very explosive. The little plastic bottle doesn't contain enough oxygen to cause an explosion. Good luck getting the flame through the tiny spray nozzle while spraying fluid out of it. Physics are against your story. While calling shenanigans on this I figured I'd consult youtube. If this were possible, there would definitely be videos. The only videos are the tins of lighter fluid literally doused and burned from the outside in. Totally different, that features boiling fluid exploding a tin.

    You can imagine the rest.

    No I can't. There's no oxygen in the bottle. I can see people being burned by spraying too much out and creating a fireball, but I'm having trouble envisioning a scenario in which the bottle explodes without already having been on fire long enough to melt through the plastic.

    Just because you can't envision how it happens doesn't mean it can't happen. It's not that the flame burns up the stream while your squeezing. Its when you stop squeezing the can and it sucks air and burning fluid up into the can. I have a co-worker whose kid did this and the can exploded and gave him 2nd degree burns plus a few cuts on his hands from the metal.
