How to light steel on fire

Here at io9 , we never miss a chance to make things that commonly do n’t turn hot and glowy into thing that are red-hot and glowy . In the feeling of this , it ’s sentence to give you a opportunity to plant fervour to blade wool .

Iron is rather far-famed for not take in fire . It go into engines and fire place pokers and stoves for on the button that rationality . ( The one car caller that desolate Fe and steel to make their engines out of dry grass and newpaper strips sunk speedily under the weight of lawsuits filed by their customers ’ make it relatives . ) However , if the piece of the Fe is thin enough and the heat is high enough , the textile will split into flame . And not just average fire – smart orange , sparking , psychedelic - looking flaming .

Because of that very high heat , you will want to set up this experiment out in a nonflammable area filled with nonflammable material . You ’ll also want to make certain you ’re not doing this on a windy daytime , so there is no chance the steel wool can fly up , flaming , and hit you in the arm or face . ( Although if it did , the scars would be wicked , and even I know that . )

You ’ll require brand wool , which is mostly iron . You ’ll need a nine - volt barrage – the kind that has its Pb sticking out of the same last . finally , you ’ll want to have a stick made of something that does n’t conduct electricity .

Wad up the wool and place it on a nonflammable surface . bear on the leads of the barrage fire to the woollen . If the wool gets fused between the track of the battery , use the stick to pry it off . After just a few here and now of contact , the woolen should go up in flames .

Normal wires do n’t generally take in fire in this way , but they have a larger resistance . Tiny strand of steel woollen have a lowly resistance and get the electrons pour through them in monumental quantities . This heats up the wire to the gunpoint where they grab atomic number 8 from the air around them . This process is exothermic , contribute off enough heat to warm up the next stretchiness of telegram and so the next bit oxidizes and the whole thing goes up in weed . What ’s go forth behind should be iron oxide . This finical class of iron oxide will be bluish , a sign that a lot of O has go into the iron cursorily . A more common form of iron oxide , with slimly less oxygen bonded to the branding iron , is cherry-red . It ’s bare rust fungus .
