Burning magnesium in dry ice



Declan Fleming shows you how to prepare and demonstrate burning magnesium in solid carbon dioxide (dry ice). This dramatic and beautiful demonstration shows that oxygen isn’t always a prerequisite for fire and reveals carbon’s place in the reactivity series.

    So the point of this was…
    There's more cold in a block of dry ice than heat in a spoonful of burning magnesium?

    You'd think that he'd show or mention the chemical equation for the reaction.

    Didn’t even penetrate it. Horrible experiment

    Crazy thing is this is a type of thermite reaction

    CO2: You gonna be franked bro.
    Mg: Nope.

    For some time i thought dry ice will transform into gas

    Is there a reason why you did not explain the reaction, i.e. oxidation, and exactly where the oxygen came from? ARGH!

    Is that how Sauron created the one ring?

  14. Pete Wilson Avatar

    WRONG AGAIN. It's the oxygen being rippid away to firm magnesium oxide, leaving the carbon behind as a dark soot on it.

    You put the lid on backwards

    Congrats, you made the tesseract.

    Does cold air comes out of the dry ice while it's in the process of burning ?

    i want to put dry ice in my butt

    "shouldn't be transported in a car" tell that to companies like Volkswagen where the engine block is made out of magnesium lol

    Does the reaction for magnesium carbide or magnesium carbonate?

    can you not put annotations on the part i'm trying to watch …..

    I don't know why but hearing that saw cut thru that ice makes me cringe! I get chills running up and down my spine. I don't like it!

    I was actually hoping the dry ice would start burning. I heard that hot Magnesium will form Magnesium oxide by stealing Oxygen from the CO2 bond. So the CO2 would be ignitable in that way.
    Does that not happen at all?

  27. Tim Lewis Avatar

    Well the magnesium would snatch the oxygen from the CO2, similar to the way the thermite reaction snatches oxygen from iron oxide to give to aluminium.

    Now what would happen if you lit magnesium ribbon under sand? Since silicon is an analogue of carbon I'd assume something fairly similar would happen

  29. Yiu Yeung Kan Avatar

    Basically, the reaction was: Mg(hot)+CO2(frozen) => Mg(hot)+O2+C=>O2Mg+C, right?

    where do you get dry ice, where do you get magnesium, where do you get liquid nitrogen? guys if i ask one of these things they would hand me to police for terrorism 🙂

    looks more like light kinda cool too
