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

Click For Summary

Discussion Overview

The discussion centers around the claim of lighting water on fire, prompted by a video that allegedly demonstrates this phenomenon. Participants explore the validity of the claim, considering various explanations and personal experiences related to the topic.

Discussion Character

  • Debate/contested
  • Exploratory
  • Technical explanation

Main Points Raised

  • Some participants suggest that the video may have used white gas or lighter fluid instead of water, arguing that the claim is nonsensical.
  • Another participant proposes that pan searing flour, a fine powder, could have been added to the water, which might have burned instead of the water itself.
  • One participant expresses skepticism about the video's credibility, labeling it as a trick and a waste of time.
  • A participant shares a personal anecdote about being able to light water due to natural gas dissolved in it, describing a brief burning effect observed during a hiking trip.
  • There is a critique of the video's presentation, particularly regarding the videography and the claim about water boiling at 195°F.

Areas of Agreement / Disagreement

Participants generally disagree on the validity of the claim that water can be lit on fire, with multiple competing views presented regarding the explanations for the video and the feasibility of the phenomenon.

Contextual Notes

Some claims rely on anecdotal evidence and personal experiences, and there are unresolved questions about the conditions under which water could potentially burn, including the role of dissolved gases.

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...
