Hello, everyone. I’m Wang Gang.
I had a look at our videos.
Our fans have been talking about the water in danmaku comments for the last 100 episode
Why do we keep the water flowing?
Why not turn it off while cooking?
Today, I’m going to explain it.
Actually, for this reservoir...
The water in here has to be cold.
Because we often need to add cold water into the wok during cooking.
Can’t be warm.
If we turn it off.
There is a hole underneath.
The heat comes out through here.
Then the water in here will…
Without cold water coming in,
after a while, the stagnant water in here will boil.
Say we want to rinse our hands like this.
It won't be possible if it's boiling hot
If we turn this one off,
the water could run out.
It looks like this when it’s empty. It's removable.
This container could be scorched.
The heat resistance sealant could eventually fall apart
Melted by the heat
In the end it would damage the wires inside
That would be very dangerous.
In this vide, I prepared an (experiment)
I'll turn off the faucet, and keep the heat on.
And I'll show you the result.
First one. Faucet off.
There is water inside.
Let's see how long it would take for this cold water to boil.
As for the other one, let's leave it empty. See what is it going to look like after heating without water.
First, we fill up the wok with water.
Because it can’t be heated for too long when it’s empty.
Then we fill it up.
Ok. We turn it off.
Let the burner run.
We could touch it on the side here.
It feels hot already.
It was only heated for about 10 second and the bottom has started to get very hot.
The water temperature is increasing gradually.
The water in the wok is about to boil.
Ok. The water inside is getting hotter.
The water (came from well) is now at around 10 °C
For those of us who cook a lot,
It’s normal to keep the burner on for 1 to 2 hours
Now the water in this container is about 30°C.
Almost 40°C.
Honestly, I've never tried to boil water like this.
I didn't dare.
Master would scold me.
And the boss would cut my pay, if he sees it.
It should be my first time doing this.
Now it feels a bit too hot to touch.
It's probably at 70°C-80°C.
The water is getting cloudier
Seems like it's about to boil.
Ok. After about 30 minutes of heating,
Without running water, now it is...
...almost boiling water.
It can’t be use for cooking.
We need cold water some dishes.
Ok. We pour away the water.
You could see, the remaining water boils away instantly.
I assume it will be scorched very soon.
The container will be scorched within 5 minutes.
Ok. The stainless steel has warped.
Ok. I'm turning off the heat to show you.
If I put cold water in it right now, there would be a lot of steam.
Do you hear this sound?
The water is already hot.
In other words, if we do not put water in it,
It will be scorched. Already scorched.
This is the result of our deliberate dry burning.
Let us take a look at this.
This is the container that normally has water in.
Compare them
This one, if we do not put water in, it will be scorched.
In a standard kitchen, this one is for running water.
Then at this place
We do not move it.
Use this one only.
There will be another container here.
The water in here is for rinsing the wok.
The water in here is for cooking.
So we always keep it on
so that we have water running
OK. The experiment is done.
We wasted more than a half of cylinder of methane
Through the experiment, we can draw a conclusion.
It is that we have to turn on the faucet and keep the water running.
Otherwise, the water inside can get very hot.
That means we can’t use it for cooking.
There has to be enough water in the container.
If left empty, it will be scorched.
Once this area becomes damaged from overheating,
The heat resistance sealant inside would fall apart
After that, this side here will be burnt out too.
This range will collapse.
So we have to keep the water running.
Hopefully you'll stop commenting about me 'wasting water'.
Ok. That's it for this video.
Bye!
