Well said constant thinker. Maybe we need a professional semanticist. I wonder when you translate burn into German you get a different meaning.

If you want to see something that looks like water that burns, get some highly concentrated alcohol solution and put a match to it. It will burn, and it LOOKS like water!

Yipee! Problem solved!

One of the products of alcohol combustion is water.

Problem with that is that with some alcohols at various concentrations the color it burns it will be washed out by the ambient color. Trust me I've burnt myself doing it and it hurts.

You can use alcohol for a make shift bunsen burner. Take a glass vile and some sort of wick (napkin can work, but it tends to burn to easily).

Corvettaholic,
Ethanol has hydrogen, carbon, and oxygen in it. Throw some vodka on a fire what happens. It burns very fast depending on concentration, but from my expierence very fast. Interesting post made me think Corvettaholic. I'd imagine that your COHh would burn. It would just requires more oxygen. Ethanol is C2H5OH. I'd imagine "burning" it would look something like this:
C2H5OH + 6O2--->2CO2 + 3H2O

Correct me if I made a mistake.

OK!  ;D
C2H5OH + 3O2 ---> 2CO2 + 3H2O

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.

WOW- I was wondering why my scooby snack count jumped from 4 to 5! So much credit for such a little correction (I wouldn't have mentioned it if he didn't say 'Correct me if I made a mistake'!)- thanks ;)!

   so are you guys saying that when hydrogen and oxygen come together there is no "burning".  because i've been told different.

  i've been told that a hydrogen-oxygen reaction at first burns. is this then incorrect?

   please explain

North  -  of course hydrogen H2 and Oxygen O2 burn:

2H2 + O2 + heat > 2H2O + big bang


But what these guys are saying is that the H2O then will 'burn' no further as the reaction (2H2 + O2 > 2H2O)  is fully complete.   The '' marks around the word burn are there because alot of the discussion has been about what 'burn' really means.

hey brothers  :) :)Help me solve this problem: Why doesn't water burn???
water is the oxide of hydrogen so essentially it is the product of a combustion reaction, thus it has already been burned.

edit: dam ^ he got to it before me.
