Elemental Extractions 7: Nitrogen Part 2

Part 2 of the nitrogen video, the 7th in the series. Featuring liquid nitrogen! I could make an entire new series on all the cool stuff you can do with LN2...

In Plant genetics, liquid nitrogen is actually quite commonly used for DNA extraction. You dip plant parts (e.g. leafs, petals, roots, etc) into your liquid nitrogen and then you grind it into a fine powder. Through downstream processes you can obtain the DNA in a concentrated form and do all kinds of amazing things with it!

Didn't know that led thing yet...

[EdwardTriesToScience]

The reason why the yellow led is orange, is because the voltage is slightly too high, so it heats up, and hot leds try to go red.

Man, sure wish I had a proper Dewar flask.

@10:00 I think it is best to call that 'liquid air'. Pure liquid oxygen is notably light blue in color.

[Taha-hvyj]

This is amazing you can extract xenon Krypton and argon fron atmosphere anddd you can make liquid chlorine!!!

Cool stuff! Have you ever tried making nitrogen ice-cream?

[davidcrunkmd]

I'd love too see you ad some toner cartrige particles to the liquid nitrogen and put it on a magnetic stir plate!

[schelsullivan]

Is it true that liquid oxygen can be pushed around by a magnetic field? But liquid nitrogen will not? Would have been cool to test that liquid dripping off the can with a magnet

[swabianscience]

That thing about nitrogen being unable to be compressed into a liquid really interests me. I haven't found any phase diagrams of nitrogen online, but from what I have seen it looks like it gets supercritical. It still would be possible to store it under immense pressure, so that, when opened, the supercritical nitrogen just expands and cools itself until it liquefies, wouldn't it? It would still be a very bad idea...

Hey I know that there are better ways to make nitric acid. Do you think it is possible to make nitric acid via sulfuric acid, using the 1st nitrogen extraction method that you did and the finally reacting or bubbling it to SO4 and H2O2 to make nitric acid?

Can you try the balloon experiment again, but first coat it with some type of light oil like vasoline or baby oil.

Kelvin is intensity, or the speed of which the matter moves. Your television is a few thousand kelvin less than required for fusion.
