Sodium gas... OMG ITS PURPLE!!!!

Thunderf00t - 2016-02-20

Sodium gas... ITS PURPLE!!!
well at least when its hot it is!

Ill probably make a more involved video on this sometime, but for the moment... this is just what science can look like..... SURPRISING!!!


I wont be adding this video to the pateron supported stream, but many thx to all those who support this channel that way!

+One___ And_Done Back in high school, my chemistry teacher lost some of her hair while she was heating up some chemicals. It was quite entertaining to watch (luckily she wasn't harmed... aside from needing a haircut afterwards).

I know he was just getting excited too and wanted a better look, just not in front of the camera might have been a better angle to look from. :D

Joey Verhaar - 2016-02-20

Are you the first person to determine gas sodium's colour?

captnhuffy - 2016-02-20

+Joey Verhaar Open your physics text book. The spectrum, including sodium's output, is listed on the inside of the front cover. Optical signature (wavelength) is a fundamental physical property known for everything that is possible to control & test for.

chromarti - 2016-02-20

+captnhuffy Indeed, he is just populating the 4s energy level (purple), rather than the usual 3p energy level (orange). But its fun nonetheless!

Lajos Winkler - 2016-02-21

+Lilliath It is a known fact, but it's not very famous one because it's quite difficult to reproduce it, as you can see.

MisterLepton - 2016-02-21

+Lajos Winkler it's not difficult to reproduce. I was wrong on my previous comment and chromarti is closest to being correct. Damn, I didn't realize how just 4 years out of school can cause you to forget so much. It looks like the only transition capable of producing those lower wavelengths is 3p (1/2) to 3s (590 nm). Check out this website:http://www.phy.davidson.edu/stuhome/phstewart/IL/sodium_raman_scattering/theory/sodium_theory.htm

And all that's required to produce plasma is heat. A "current" is not necessary.

I worry that you're going to light your hair on fire, dear god man, get a scrunchie!

Liarra Sniffles - 2016-02-20

+theendofit "A piece of her scalp was caught in the motor."
Her hair being bulled was not what caused the scalping, it just brought her head down into the gears, which preceded to scalp her.

Read your own sources m8.

theendofit - 2016-02-20

@Liarra Sniffles just google "girl scalped when her hair got caught in"
youll get 100's of stories about girls with long hair geting hair cught in some machinery.
the point is not the excat 1 for 1 situation has happened its that it can happen and simler things happen as nick said it would just rip the hair out and nothing else.
there is also cases where somones neck was snaped when thier hair got cught and it yanked thier head.

these are incredubly rare things but with a population of 7 billion on earth even a thing that happens to.0001% of pepole a year  or 1 in million pepole it would still happen to a 1,000 pepole a year.

Nick Skarvig - 2016-02-20

@theendofit
Despite it not being a gear but instead a drive shaft you are right. The drive shaft actually makes sense because it would be able to grab and pull at the same time since it would act very much like a clutch plate. The one incident cited on that site was apparently an issue with improper assembly instead of a standard danger.

Lighting long hair on fire with an open flame you are currently holding is a more prevalent danger in my opinion though.

Liarra Sniffles - 2016-02-20

@theendofit You misunderstand my point, the girl's hair did not pull her scalp off, but it did pull her head into the drive shaft which then got a grip on her scalp and ripped bits of it off.

I do not think it is possible to rip a scalp off using the hair on your head, as the individual hairs are too weak and the bunched hair is too strong.

The problem doesn't change with force applied either, if you could pull hard enough to rip a scalp off with enough bunched hair to stop it from just ripping hair out, you would probably just pull the whole head clean off/pull the whole person along depending on how hard the force actually is.

Out of all the dangers of a theme park, being scalped is not nearly the most likely.

ssholum - 2016-02-21

+Nick Skarvig
I remember a story where a woman's hair got caught in an auger and it scalped her, but my source is TV...

It's not an outrageous claim though; human hair is actually pretty strong, it's the connection to the scalp that's usually the weakest point; all it would take is to get enough hair caught for the force applied overcomes the connection of the flesh to the skull (and other flesh) without overcoming the collective load tolerance of the hair roots (which, being parallel, would ideally end up with the load applied equally to all the hairs, though it wouldn't be quite that simple in reality (some would be under more tension than others)).

I'm not a mechanical engineer, so forgive my poor vocabulary regarding material strengths, joints, and loads.

chromarti - 2016-02-20

By heating the sodium gas you are populating the 4s energy level. When the electrons decay down to the ground state (3s) the photons emitted have an energy of ~3.1 eV. This corresponds to a wavelength of ~400 nm, which is purple! I love your enthusiasm and 'mad scientist' experiments. Keep it up!

p.s. Your emission spectrum also shows a peak in the yellow/orange (3p spin up/down to ground state), which is the emission you see from street lights in the UK. There is also a broad peak in the red/infrared, from heating the glass.
p.p.s. If you use an interferometer and electromagnet you can resolve the quantum-mechanical effect of spin-orbit coupling in sodium.
