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

Click For Summary
SUMMARY

The discussion centers on the claim of lighting water on fire, which is deemed implausible by participants. They assert that the individual likely used white gas or lighter fluid instead of water. Additionally, the introduction of pan searing flour is suggested as a possible ignition source, although it is ultimately dismissed. A participant recounts a personal experience in New Mexico where water containing natural gas vapors was ignited, demonstrating that while water itself cannot burn, certain conditions can create a flammable vapor.

PREREQUISITES
  • Understanding of combustion chemistry
  • Familiarity with flammable liquids such as white gas and lighter fluid
  • Knowledge of the properties of water and gas mixtures
  • Basic videography principles
NEXT STEPS
  • Research the chemical properties of water and its interaction with gases
  • Explore the effects of different flammable liquids in combustion scenarios
  • Learn about the principles of combustion and ignition sources
  • Investigate videography techniques for effective storytelling in science demonstrations
USEFUL FOR

This discussion is beneficial for chemists, educators, videographers, and anyone interested in the science of combustion and the properties of flammable materials.

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...
