One of the farmers I worked for had a Gopher problem, they were everywhere.
thousands, and what I had to do was grab some grain
and add a little Anti-freeze, and mix them together.
Then we placed these at the gopher holes and then they would eat them,
And finally die from it.
What brings me to the point, that the stuff is extremely toxic and it tastes very sweet.
So if you have animals in the house, and have anti-freeze around, they will eat and die.
so please be very careful, if you are ever going to experiment with anti-freeze.
So I still got a lot of requests in the comments for liquid nitrogen experiments
and when I was scrolling through it, I found this comment from “Sagisu12” that says:
“Can you freeze anti-freeze in liquid nitrogen?”
That is a good question, anti-freeze will freeze?
And about 800 of you gave this comment ‘a thumbs up’. so apparently you want to see this very much.
So I took ethylene glycol, so we can test that suggestion.
So in the preparation for this experiment today, I did a little research on anti-freeze,
and apart from the fact that it is extremely toxic, has a very wide area.
It can be as hot as 130ºC. and as cold as -37ºC
And I say Celsius to all international viewers, give me a thumbs up if you appreciate it.
Will this stuff actually freeze, will it expand, will it turn into a kind of mucus or gel or will it turn into a kind of frozen anti-freeze crystal?
That is the reason for this experiment today! Let’s find out what anti-freeze does to liquid nitrogen
For this demonstration I thought it would be nice if we use this interesting looking dish.
This is called a ” quaich ‘and it comes from my good friend George Calver from Scotland, thanks to George
We will use this today with anti-freeze and liquid nitrogen.
Let’s start!
That is so beautiful
So beautiful
That, my friends, is how anti-freeze looks like.
But you really do not want to put this in your mouth, it is extremely toxic.
As good as what it looks like,
Do not drink it!
Because the way it kind of shines, let me wonder
What if we shine on it with a UV lamp?
Wow! That is really cool!
That is neat!
A little UV light and a little anti-freeze and you have a homemade glowstick
Who would have thought that?
You can now control your glowstick.
[chuckle]
This fluid is very interesting, and I actually thought it was much thicker.
More like ‘glycerin’
But if you look at it, it moves just like water.
But if in my finger stop and move with it,
it feels more like an aqueous sugary syrup.
It is very sticky
Let’s start with our experiment. Glass dish with liquid nitrogen, here we go!
Here we go!
Look at that bubble
For the many times we have used this glass dish,
Am I surprised that it is not broken yet.
It holds it very well!
This happens every time!
If the liquid nitrogen has cooled the glass almost in the same temperature,
It starts cooking very quickly, it becomes very violent and
and usually splatters in all directions
oh yes, there it goes! watch all the flying drops
See how much nitrogen it needs to cool the dish!
It was more than half full. now has already dropped to about
a quarter of the glass!
So,
The difference is that the glass is now very cold, and we can add more nitrogen.
This nitrogen is made at home, fresh from the ‘dewer’
Perfect!
So it looks like the dish is ready, let’s go on and on
bring the quaich down.
Okay, the moment of the truth guys!
This is purely anti-freeze
The first test is 100% anti-freeze
Let’s see how that reacts to it.
I’m kind of nervous
Because this dish is hot compared to that Nitrogen.
Woow! My handshakes froze.
And there goes the …. Ha!
I already knew that a bit, that was going to happen.
But look here, look down at the bottom.
You can do the antifreeze
looking around it.
That was a total failure
And my shirt is cold
But we can still see what happens here
If you look at the anti-freeze, it looks like ..
it turned into a kind of …
Light greenish gel
But is it gel or is it a solid?
If you look at the slo-mo, you can actually see it
my fingers froze,
my finger tips are frozen
And I had to let it go
Liquid nitrogen repels the skin faster
if you do not wear gloves, if you do wear them
it freezes solid and keeps the cold in contact with my skin.
So wearing gloves is perhaps against productive.
Oh yes, look at that.
It is beautiful
its very, very beautiful and it was an accident
Yep, that’s super hard
Look at this stuff down here
I need to find a way to get it out.
Woow, yes look, it froze my fingers solidly.
it just happens right.
Oh! that is cold
Ha!
There is a piece of chunks in here
Oh yes, there you have a nice piece of chunk or anti-freeze
That is really solid.
WOW!
AH! it freezes my fingers!
It broke right like outbreak glass.
and then it remained stuck on my fingers and froze it.
like a cyrogene napalm
that’s mean stuff!
You can not easily get rid of it very sticky.
This stuff is simply powdered, check this out!
Check this out guys, we have just made anti-freeze snow.
Oh look, it drips!
It warms up again and changes it into slime
Anti-frozen mucus
Aw, you can push it off, you can let it melt and you can scalpe it
it’s like gel, and it’s a bit transparent, it looks a bit like ..
The ninja Turtle mucus made from Borax
In one of my other videos
This stuff starts to warm up, and it becomes opaque, interesting again.
The warmer it gets, the more opaque it becomes.
It looks like lime sorbet ice cream.
I wonder what smell it has.
It has a slight sweet smell, but for the most part I can not smell it well.
What does it taste like?
Just kidding!
[laughs] We’re not going to try it, okay
We still have a little nitrogen left here in the container.
What would happen if we put it directly in the head with antifreeze?
Let’s find out!
Ohh cool!
Look at the top here, check this out
The nitrogen actually floats on the Anti-freeze
and forms this crusty layer
That is Bizarre, it is like making little islands of ice.
Let’s do a little bit more this time
Yeah, so the nitrogen floats on top of the anti-freeze,
and then it freezes a crusty layer on top
It is almost like a poisonous creme brulee
Let’s add the rest.
The top in ice changes almost immediately
Or whatever it is, ethylene glycol
If you look here, you can see that the anti-freeze,
Almost untouched on the bottom, but then it freezes and forms a layer here
And we have bubbling nitrogen on top.
So, we have kind of frozen antifreeze
and while it thaws it forms a very sticky, slimey kind of syrup
Let’s make it a kind of frozen pound of antifreeze
Here the boys update: We know that antifreeze can completely freeze.
But according to the container here, if we add 30% water, that gives us maximum efficiency.
So I added the container with just a little less than 1/3 of a cup of water
and if we fill the rest with anti-freeze
In theory, we would have a 70 – 30 mix
and we can see how that reacts
A solution of anti-freeze and water has a very wide temperature range
and that is very important because most car engines have water cooling
If you only used water, you could have different problems:
If it gets too cold, the water will freeze and block your radiator
and if it gets too hot it can evaporate in steam and the engine can suffer extreme damage.
But if you add anti-freeze to the cooling, the temperature range can increase
Because it has a much lower freezing point and the buying point increases dramatically.
so as to retain the interest of my previous homemade liquefied nitrogen,
I’m going to cast it in quaich, and let it cool down
and then we take this anti-freeze solution and pour it in slowly so that we can see the reaction up close.
Ok so here we go, our quaich has cooled down, we have small pieces of my glove floating around here
Let’s go further and take our anti-freeze solution and drop it downwards,
Here we go!
aw, great!
It seems to be bubbling at the top, and then it sinks to the bottom.
Will it freeze? that is the question.
I am not an expert, but I am sure that the answer is yes.
Check that.
he is like a bubble made.
It is almost hollow inside, a bubble made of water and anti-freeze.
Oops!
It is apparently very weak
I’m going to dribble into it to see if that makes a difference.
That is pretty cool
At the beginning it seems that the antifreeze is a kind of
bubbles and floats on top.
Come, check this out
That is neat!
That seems pretty cool!
Oh, did you notice that the bubble was splashing out?
While you look at it, I shine some UV light.
Woohoehoe
Look at the way how that lights up.
Woow
After this stuff is frozen, it just looks like crystals from Kryptonite.
Yes. that is really hard.
Water when added is still not a lot for liquid nitrogen.
So will liquid nitrogen antifreeze freeze?
I think the answer is self-evident, yes it will, and we had a lot of fun while running today
We also made anti-freeze snow. I did not even know that, that was possible.
You can also use UV light to illuminate this stuff like a glowstick.
All super cool experiments, and all because you asked for it.
And thank you very much ‘Sagisu12’ for the suggestion of this experiment today.
and all 814 of you who gave that comment a thumbs up.
Keep an eye on your youtube inbox, Sagisu and I’ll send you 25 bucks.
And thank you to all of you guys for watching this video today! I hope to see you in the next video
See you then.
I think that thing is stuck to my work table
I can not get it off!
