@DANGJOS It has been pointed out previously that I misstated the temperature, I had another number in mind when I did so, and there are some disagreements as to the exact temperatures involved none-the-less. Also depends on the scale of course.

@mrericsully -- When the water hits the oxidizing magnesium, the atoms in the water molecules bust apart from each other because of the energy imparted to them. Immediately, the hydrogen oxidizes again with the oxygen, again releasing energy as heat and light. What is that specific process called? Is that a redox/oxidation-reduction reaction?
@MetaSethical To be honest the best thing to do would be to label each individual reaction and consider it a step-wise process. I don't think it is common to name the whole series of reactions as if they were one.
2H2O --(heat)--> O2 + H2 decomposition & redox
H2+O2 --(heat)--> 2H2O synthesis & redox [though technically you are correct it is oxidation-reduction]
2Mg+O2--(heat)--> 2MgO synthesis & redox
I've never heard of a reaction that occurs in several steps being named as a whole.
@mrericsully I make sure they have Mg in them. But even though some might not appearently sparkle like Mg sparklers, they work in my certain application.
@PillarOfChrist This is not a great chemical explanation of it, but basically the Mg wants to bond to the oxygen so much that it strips the oxygen away from the water.
@lordanjan1 I don't know of any. Usually it is left to just burn itself out. Sometimes it is contained in sand or dirt and smothering it might help.
If you look for a video of the fire on the USS Forrestal, part of why they had trouble putting it out and eventually had to just let it burn itself out is because parts of the aircraft [mostly the wheels] were magnesium alloys.
@joblessalex A small quantity like this will not, but larger pieces will. Pieces underwater before ignition are obviously harder to light, but it can be done.
@mrericsully Ok then. I just got a 25 gram roll like yours. I'm just getting in to chemistry and enjoy explosions and fire magnesium suits me very well!
Ahhh! We worked with this in chemistry, except we made magnesium into MgO so we could add H2O to it. Although, We DID put Mg into HCl, it was purty cooool (:
@thecallofdiluted It is usually magnesium and/or aluminium metal and an oxidizer used in flash-bangs [stun grenades] in real life, on which the call of duty munitions are based.
@swordlord285 It can do damage to your eyes because it is so bright but it depends on quantity of Mg as well as how long you look at it of course. Also, UV exposure is a concern.
@nar0001 Yes and several people have pointed out the clutter as well. Having said that even though the sparks are hot they have very little heat energy total and are unlikely to burn through the tube.
@soadfansoad No, because that reaction is incredibly slow since Mg is not very reactive with water. Search for my video "Alkaline Earth & Alkali Metals in Water".
the question is why the color is being emitted. the answer is the electrons in the magnesium atoms are going from ground state to excited state and back down to ground state at which they emit light. it's how fireworks work,
@noglobwarm96 Yes, that is true, although I would clarify your answer and say that it is how fireworks get their colors and most of the light they emit.
However, that wasn't really the principle I was trying to discuss here, rather I was showing that Mg fires are hard to put out by out normal methods. Water will not put it out and in another video I show that Carbon Dioxide will also not put it out. Usually about all that can be done is for the fire to be contained.
@vitaminwasher No because the camera I recorded this on is unable to record UV wavelengths, not only that, but your screen cannot project UV light either.
My teacher told us a week ago never to burn it, but he didnt give us a reason, which OFC made us wanna burn it. and we burned a small piece today, and almost fucking burned down a table. We couldnt put it out XD
@RazorRabidz Another reason, other than it being nearly impossible to put out, to be careful burning it is that it is very bright and an cause eye damage and it does emit UV radiation.
Goggles and looking off to the side really help with that part.
@vanillapuddingluvr It has been pointed out previously that I misstated the temperature, I had another number in mind when I did so, and there are some disagreements as to the exact temperatures involved none-the-less. Also depends on the scale of course.

@twistymcslide My guess would be because of the heat it gives off. Many aircraft engines are made out of magnesium to begin with which would cause issues. Plus it is really difficult to get large pieces of magnesium to ignite because it does such a good job at conducting the heat away. Lastly, it would be harder to refuel because the magnesium is a solid and would probably be inside the engine. So it might be possible, but there are a lot of hurdles to overcome and better alternatives.
@mrericsully . what about a titanium chassis and a plasma cutter type ignition system . you could easilly addon extra tanks to supplythe water and oxygen . my major concern would be if it burns cleanly, and or if thrust is a byproduct of the reaction . anyways. thank you for your reply. if you make millions off the idea. maybe shoot me a few bucks so i can buy my mom a house. be well .
We do make engines that burn metals they're used for large rockets. also aluminum is usually used in such cases because it packs more energy per KG than most other metals.
@ace2a66d20 I'll trust you on this is isn't really my expertise and I haven't looked into it a lot. I will say that it isn't very common and that it isn't the primary focus of all of the research that I have seen.
@d1drifter87 I agree that you should not stare at burning magnesium, but neither I nor my students look directly at the burning magnesium. Also, I am wearing goggles that offer UV protection.
this teacher said that magnesium burns about 1500 degrees Fahrenheit but he wasn't even close in reality it actually burns in excess of 5700 degrees Fahrenheit
We put a old VW engine block on a beach bond fire one time, it was made of Magnesium, good times! Some of those older car rims are made of magnesium just dont stare at the fire. LOL.
I've not heard anyone talk about using metals as a fuel. Considering the energy it takes to start it burning, not to mention the energy in the refining process, I don't think that they would be very efficient.
aluminium is being considered as a fuel by nasa, the idea is that you can find it on mars, unlike kerosene etc. it ignites quite easily when in a powder mixed with lox.
I got into an arugement with someone on YouTube a couple years ago about Mg being used in flash or incendiary bombs. In John Emsley's Natures' Building Block's book he states that Mg is used for both. I know for use that it was used in incendiaries because it is so hard to put out a Mg fire. Although I do believe it was used in some flash bombs, the primary component of flash bombs was/is(?) phosphorous.
my school did this when i was in 7th grade but the teacher only burned a small part of it b/c my school back then was cheap. and magnesium makes a great light for filming in dark places but be careful.
The UV from burning Mg is not great for your eyes, I thint i would have wanted Welding Goggles if id have been watching Mg burning for that long.. But i enjoyed the Video...
I don't cover oxidizers or reducers with these students until much later in the year, so it has to be over generalized at this point. For them it is interesting.
He got a few things wrong, it was white phosphorus, not magnesium that was used as an incendiary weapon in WWII. Magnesium was however used extensively in illumination rounds fired from mortars but they were not deadly.
Also on 4th July, the sparklers that kids use do not use magnesium but in fact extremely fine iron powder to create the sparks.
In fact, this teacher really needs to get his facts straight or his students will lose faith in him.
Both white phosphorus and magnesium were used in incindiary weapsons in WWII. Magnesium was used because it is near impssible to put out a magnesium (or many other metals for that fact) fire.- See John Emsley's "Nature's Building Blocks" for a reference on this fact.
Also, you are correct that most sparklers in the US no longer contain magnesium, but they used to. Also, it IS still possible to purchase some with potassium chlorate or perchlorate and magnesium at specific fireworks stores. Also, just because it is not common in the US to find sparklers with magneisum they are still common elsewhere and the safety concerns are pretty much the same when speaking of sparklers and their high temperatures. Magnesium or iron kids and adults still get burned.
OK, I went a bit far with the "faith of students" but you just seem to get so many things wrong I got the idea you hadn't done your research.
I was informed that magnesium sparklers were obsolete now for their storage risk and other aspects. Also magnesium was only ever used in the thin casings of incendiary bombs, thermite was the main component, Mg was secondary. But that was misleading on the part of "Nature's Building Blocks".
It seems you did the research but the sources let you down.
that was the most awsome science experiment that I saw, Tell your science teacher jtypo said so. Also that I am on youtube if he wants to watch. :) Very cool vid!
yes I am. I am in my fourth year at this district, this video was filmed my second or third. I am still filming as many demos as possible (even if they are repeats) an posting them to YouTube as often as possible.
wow this stuff is amazing my dad would tell me if they were able to put the old magnesium rims in a lake they would litterally burn still underwater. thats hella amazing. and also, thats y i love science. and anything that has to do with fire. im a pyro.
We just burned some in my chem. class and my teacher told me it was about 2000 degrees Farenheit. Why we give kids metal burning over 2000 degrees I'll never figure out.
I agree, however there is a large difference between temperature and heat. Sparlkers burn at very high temperatures, but because they are tiny have very little heat energy. A bowl of soup might have the same temperature as a spoonful of the same soup, but the bowl has more volume and therefore greater heat energy.
With a tiny strip like this it would probably extinguish it, but larger pieces cancontinue to burn underwater. Look at Netexperimente's version of this demo [I don't recall what # it is, but they are under my channels that I subscribe to].
It can actually reach temperatures over 5,000 degrees Farenheight

I don't think that would work. Class D fire extinguisher or contain and allow to burn out.
