There is a video in Youtube
filmed by a company that makes chewing gum
showing that their chewing gum can turn water in to ice.
They say that you put the chewing gum in the water
and the wather just turn in to ice.
If you want to see the video
just click in this box here.
I tried to buy this chewing gum to do the experiment
but I didn't find it.
But I found this screwdriver here.
This screwdriver is magic
and can transform this water in to ice.
It'j just touch the water
an it's transformed in ice. Do you want to see?
If you watched the chewing gum's video,
you'll see that the same happens here.
And what's the secret behind this?
The secret is that the substance that is here
is not water.
The substance here is called sodium acetate.
The sodium acetate is liquid until about 55 Celcius degrees.
Below this temperature it solidifies.
The fusion point is between 50 and 60 Celcius degrees.
And what happens to sodium acetate?
You heat it in the microwave
and let it cool down in a calm place.
If there is nothing to disturb, not even a grain inside, no knocks
it will be liquid at the environment temperature.
Its temperature will cool down
and will be bellow the fusion point, but it will not solidify.
It will happen because there is no disturb, no solid grains inside
nothing that hit the substance and force it to solidify.
It needs stimulation to solidify.
The same happens to water.
But the water solidifies easily.
Any grain, any hit makes the water to solidify.
But how I made the screwdriver to solidify the sodium acetate?
I put a small grain of sodium acetate in the point of the screwdriver.
When you put a grain in the sodium acetate
this will happen.
It solidifies very fast.
If you want to buy sodium acetate
– I see some videos teatching how to make it at home
but it's very hard. You need to mix vinegar with baking soda
and heat in the oven till all the water evaporates.
It's almost impossible. I couldn't do it.
But you can buy one like this in a chemical store. Was what I did.
It costs about US$ 9 a jar like this.
And now I will show something very cool.
Since the liquid sodium acetate
when touches the solid sodium acetate solidifies
it's possible to make mountains of sodium acetate.
More videos like this you find in the next Tuesday in the blog Uhull.
Thuuuuuuumbs up!
