Hello everyone, this is Jeff of TAOFLEDERMAUS
Since "Carsandwater" did a video red hot nickel ball with the antifreeze
A lot of people wanted to see what would happen if put antifreeze
or engine coolant - whatever you want to call it - how it behaves in a sealed
TEST TUBE and heat up with a torch
So, let's see what happens
I actually thought this one was going to be a failure. After about five minutes
of being under the heat up this very hot propane torch
nothing was happening. No color changes
Just a lot of boiling going on - a lot of shaking
now the boiling point a antifreeze
is pretty high its 387 degrees Fahrenheit or 197c
Antifreeze is added
to a cooling system of a car or a motorcycle or whatever
kind of combustion engine. It is there to enhance the properties
OF water.
The properties of water pretty amazing on their own but it has limitations.
Water has a pretty high freezing point
and a pretty low boiling point. So the antifreeze
enhances the water by giving it a much lower freezing point.
You don't want water to freeze in your engine
It will split your block right open or cause freeze plugs to blow out.
and of course you know what the boiling point to be too low
where your engine boils over
and you overheat. The other thing about antifreeze
is it contains corrosion inhibitors
and other chemicals that prevent
RUST and scale and all that stuff
You're supposed to change it out every two years or so in your engine
I think most people often neglect that.
We have a lot of boiling going on. The pressure's is going crazy in there
as the a fluid boils and we are at a really high temperature.
The pressure is starting to build up in this thing.
but unlike a lot of the other experiments we've done
We don't see much of a colour change - we don't see it getting
darker or foaming or the level rising - so this is a very unique
and different experiment.
I don't want to put you asleep so we're gonna speed this up
four times again. Just so you know and you are ready
when they're we go back to normal speed
it's about ready to blow. So standby!
let's look at the high-speed footage and see what happened on this thing
as you can see the
cap first blew off and then the
silicone plug blew out. It was kinda like a delayed reaction
Let's look again at 600 FPS
you can see that I put a foam pad underneath it hoping it'll protect the
the test tube, This didn't work out very well
but this was a another interesting one
completely different results and I hope you found it interesting
I always enjoy these - it's always a big surprise when I look at the footage
afterwards
thanks for watching. Hail our cat overlords!
