Oxygen - The MOST ABUNDANT Element On EARTH!

ATTENTION! This video shows dangerous experiments! Do not repeatthe experiments shown in this VIDEO!
So today I want to talk to you about such element as oxygen, and show its properties along the way. I think many of you already know that oxygen resides in the atmosphere and is essential for life, and is also involved in the combustion process, i.e. oxidation. Oxygen is the most abundant element on Earth, our atmosphere contains only 21% of oxygen, no more no less. The remainder of the oxygen on Earth is distributed in the form of compounds, that is, oxides, carbonates and water, though water is an oxide. We have all seen that lot’s of different things can burn down in oxygen such as wood, paper and plastic
Though if we increase the oxygen concentration then things start to burn quite more intensely. Also, like any gas, oxygen can be condensed, i.e. liquefied.
Btw things burn even more intensely in liquid oxygen. For the condensation of liquid oxygen we’ve used liquid nitrogen. The boiling point of liquid nitrogen is 13 degrees lower than that of oxygen, so by passing pure oxygen from a cylinder through a copper coil that is cooled by liquid nitrogen we can obtain liquid oxygen. The oxygen liquefaction itself looks very fascinating. Fun fact, in large hospitals oxygen is normally stored in liquid form in large tanks to save space and for easy transportation. After we’ve obtained the liquid oxygen, let’s look at its properties.
The most interesting fact is that in liquid state oxygen is not a transparent liquid, it’s in fact blue! All because of the light absorption spectrum of oxygen atoms.
Also, liquid oxygen is paramagnetic and is attracted to magnets, by looking closer we can see small droplets rising towards the magnet.
For the experiments with oxygen, we took a sponge, toilet paper, chips, tea, T-shirt, crackers and a few other items. To begin with we take a dry crust of white bread and try to burn it at normal oxygen concentration in the air.
As expected, the bread does not want to burn. Now let’s soak it with liquid oxygen and try to ignite it again. The liquid oxygen dry bread turned into a real jet cracker, even gave little traction. If we add some more oxygen the smoldering cracker it starts to burn again. Now let’s take a toilet paper and soak it in liquid oxygen and then set it to fire. I think we’ve just created a new kind of rocket fuel out of toilet paper.
In fact, in the rocket engines of Shuttle liquid oxygen served as an oxidant and liquid hydrogen was the fuel. Unfortunately, we don’t have any liquid hydrogen, however, look at this lovely tea bag! In the cup filled with liquid oxygen it doesn’t want to brew, however in the subsequent ignition it then turns into a real powder. Also, if you soak a cotton T-shirt in liquid oxygen and ignite it, it will turn into a real bomb!
Do NOT attempt to repeat what you’ve just seen! From the close contact of oxygen molecules with the T-shirt material, its combustion is magnified. The same thing happens with a cotton wool, as it absorbs oxygen very well and has a large surface area of the particles, accelerating the reaction. Though the most rapid combustion reaction with liquid oxygen was acquired with an ordinary kitchen sponge.
The soaked in liquid oxygen sponge simply disappeared when it was ignited without even leaving a piece of it as a memory. We were left with an explosive combustion.
If you like chips, think of how bad they can be for your health, how much fat and harmful cholesterol is contained in them. It is better to throw them away, so as to not poison your body. But wait, they contain a lot of energy, let us not waste that!
With the addition of liquid oxygen all the energy contained in those chips breaks out in seconds, conveniently also heating the place. During the combustion of chips, as well as everything before them, carbon dioxide is formed and hydrogen monoxide also, which is water in the form of steam.

Thoisoi now has messages in his videos: chips are bad, oatmeal is good and don't cut down trees XD

Why you no try aluminum powder? I suppose you might want to keep your fingers... lol

oxygenated old bread... weapon of mass destruction

[Dziaji]

Just started watching this channel recently. This is one of the best beginner's chemistry channels on youtube. Love the Russian accent and light humor as well!

[MushVPeets]

With a bit of liquid oxygen, almost literally _anything_ made of organic material can become a rocket.
Even my carpet. But that is alright. I have many carpets.

[androidtvbox]

The bread spinning and the sponge vanishing are epic. I loved this video. Keep on teaching us Science in an entertaining way.

[Zanek_power]

You and Periodic Videos are my inspirations to study chemistry hard so that I can understand it and like it even more.

Edit: also Cody's lab

Ahhh seeing the notification for a Thoisoi2 Video and then hearing him say "Hello errywon" is just perfect!


For real tho great content!

[gpcgamerTV]

These videos keep getting better and better. Keep up the good work!

[abdelhakim]

the only youtube channel that i watch his videos instantly when i receive the notification even if i'm at class or wc hhhh nice job (y)

[Prinzmiga]

Now i know how Michael Bay see the World... its possible with Oxygen

[thecryptidhunters]

For me these videos are like when you stare at waves hitting the beach for a while, and you start to feel like you understand how the universe works. It's crazy how much OXYGEN can do, just oxygen. A microfraction of what the world is made up of.

[cultuuedpetri]

well done, your videos are not only formidable and awe-inspiring but informative as well.props! I don't have to money to help you out via patreon, so I'm a sub and like guy. hopefully that helps.keep doing what you're doing, you wonderful Russian.

[TheToby]

Wow this is the best video I've seen on this channel!

[voopu]

How to burn a lot of calories in a splitb second?
Soak it in liquid oxygen and ignite!

[lecolintube]

Amazing! This is my favourite one of these videos! (Why is it that simply burning or blowing up things gets hits!) but the facts about oxygen & ozone at the end is really just astonishing! Love it! Thanks ;)

[cubicengineering]

how about liquid oxygen + castor/icing sugar (whchever is finer)
sugar has much more energy for mass than all else in this video, and finer grains means higher surface area

[alexanderx]

The ignition of that oxygen soaked sponge was particularly entertaining.

[kevinjaitejmontbose]

Man, I love your videos and your Russian accent. Keep up with new content. Cheers.

Eu amo esse canal com toda minha força
