A few sparklers tied together also burn under water, because they contain oxydizer and fuel in one and the same device which burning temperature is very high. Would magnesium ribbon (= fuel only) continue to burn under liquid nitrogen? Under water it doesn't. Magnesium nitride also is formed inside a pile of burning powder when oxygen from air runs out while covered by a small glass container. Adding water to it after cooled down releases ammonia.
Indeed, the sparkler has an oxidizer present. But the liquid nitrogen itself can act as an oxidizer for the sparkler (as evidenced by the production of magnesium nitride). Thus, I'm not certain it would go out. I think I should be able to test this...
Interrsting , very interesting. Our atmosphere is 20:80 ratio of oxygen to nitrogen. Stuff such as fine iron metal dust powder has been done as a fuel for ice engines and works ,, maybe a bit abrasive though" . If magnesium powder was used instead, then more power would be available because it would also combust also with the atmospheric nitrogen surely . I wonder how the exhaust operates for an essentially gasless exhaust though . it would be a negative pressure exhaust maybe . Those vacuum bombs use aluminium powder .
Not quite. Even in water a sparkler can still burn because it carries its own fuel and oxidizer much like a rocket engine in space. Unlike the match, it doesn’t need oxygen to burn.
True, it would burn in water because the sparkler contains oxidizer. However, the product of the sparkler reacting with its own oxidizer would not form greenish yellow magnesium nitride product. Thus, the formation of the greenish yellow substance is positive evidence that the sparkler reacted with the liquid nitrogen. I imagine the product of the sparkler reacting with its own oxidizer would appear white; I observed no white product in the liquid nitrogen
Yes but also no. The reason the sparkler keeps going is because it has it's own oxidizer. And it does eventually go out, but not because of lack of reagents but because lacking heat. As the sparkler is submerged in liquid nitrogen, the reagents get cooled down and so the reaction cannot overcome the temperature gradient, eventually reaching an equilibrium where the reacting can no longer keep heating nearby magnesium to its ignition temperature. Once that happens, nitrogen wins.
Indeed there is likely some reaction with the oxidizer that is occurring. However, there is also reaction with the nitrogen as evidenced by the presence of the yellow-green Mg₃N₂ product. Nice observation on the reaction stopping as it cools. You might be interested to know that in separate tests not shown here, I did observe the sparkler to completely burn out while submerged in the liquid nitrogen
@@TommyTechnetium I am not refuting that the nitrogen reaction takes place. I am simply saying that the self sustaining burning chemistry is because of the existence of the oxidizer. Without it, the sparkler would go out much sooner.
@@RealCadde Thank you for the clarification. Hard to tell based on the visible evidence. I'm not sure what the product(s) of the oxidizer would look like, but I'm imagining white colored. I didn't see any white solid in the liquid nitrogen
The nice thing about science is you don't have to believe me: try the experiment for yourself and see how it works. I look forward to hearing back from you if you do try this experiment on your own
This right here keeps kids interested in science! Dont stop makiing cool videos sir
Thank you 😊
Nice video but I am wearing headphones and the ding sound at the end destroyed my ears.
Sorry 😞
@@TommyTechnetium Np man your content is great everyone makes mistakes
@@aetius31 Thank you for your kind words. I'll try to pay more attention to the goofy sound effects I include 😜
So cool! Love these bit sized physics pieces with a cool visual & a simple explanation
Thank you 😊
Liquid oxygen next?
😳
WHOOOSH.
That's what's going to happen.
🔥🔥💥

Incredibly cool and unexpected! Thanks for sharing this TT!
Thank you 😊
Man that looks like the most refreshing glass of sparkling water
It also burns because it has its own oxidizer. If it didn't, then it would go out when exposed to nitrogen.

Break the outer covering of filament. Turn on in liquid nitrogen it acts as an inert atmosphere and prevents filament from being oxidised.
Very cool!!
Thank you
This was cool to learn
Thank you 😊
WOW
Now do one of those magnesium flashers....😊
😳

@@RealCadde Thanks for helping me look at this experiment more carefully
It’s also the case in simple water…🥛
Not nearly as cold in water, yes?
It doesn’t need oxygen?
Cool, huh?
100 % fake. It is not liquid nitrogen. However one single take is correct - a sparkler will burn since it usually has its own oxidiser mixed in.
The nice thing about science is you don't have to believe me: try the experiment for yourself and see how it works. I look forward to hearing back from you if you do try this experiment on your own
Try on liquid oxygen or chlorine
😳
