Lighting water on fire? I don't think so.

AI Thread Summary
The discussion centers around skepticism regarding a claim that water can be lit on fire. Participants argue that the demonstration likely involved a flammable substance, such as white gas or lighter fluid, rather than water itself. One contributor suggests that pan searing flour, a fine powder, could have burned instead of the water. Criticism is also directed at the video's production quality and the incorrect assertion that water boils at 195°F. A related anecdote is shared about an experience in New Mexico where hikers reportedly lit water due to dissolved natural gas, suggesting that while water itself cannot burn, certain conditions may allow for flammable vapors to ignite. Overall, the consensus leans toward the demonstration being a trick rather than a genuine phenomenon.

Whilst perusing the Tube, I found this:



What do you think? Did he actually light water on fire?

I don't think so.

He probably replaced the water with white gas, like that used in the old camping lanterns and stoves, or more likely, lighter fluid for a BBQ.

The claim is nonsense.

No need. He added pan searing flour, which is a really fine powder flour, just before lighting it. The flour probably sat on top, and as a fine powder, is probably what burned.

And will someone tell that guy that water doesn't "boil" at 195 F! And right after that, give him a lesson on videography that explains that aiming the camera at the floor while walking around is pretty HORRIBLE to watch! (I fast forwarded...it was too painful to watch real time.)
 
These are too painful to watch and a waste of time. It's a trick.
 
Member HH/SA CRGreathouse sent some related thoughts in a PM. If anyone wishes to discuss this in detail, please start a thread in the physics or chemistry forum and let me know. I'll post a link.

I saw that the thread was closed, so I figured I'd send this to you.

Regardless of what the video shows (can't see videos on this computer), I will say that it *is* possible, in some sense, to light water on fire.

When I was hiking in New Mexico there was a place where there was enough natural gas in the area (or so I was told) that water in a canteen could be shaken and lit. I can't say it was because of natural gas (though that sounds reasonable), but my fellow hikers and I were able to test this directly. We were able to light the water (actually vapors formerly dissolved in the water) and watch it burn for about 3-6 seconds with a dull blue flame. Not only did I witness our group doing this several times (new water each time; once lit it wouldn't light again) but we were able to videotape it one of the times.

I just thought this was relevant enough to mention...
