Greetings fellow Nerds.
In this video, I will show you how to make sodium acetate,
also known as hot ice.
If you don't want to watch the video you can also look in the sidebar for the instructions.
Here we start with 1 liter of clear vinegar.
Which is a weak solution of acetic acid.
Now you'll need to add 84 grams of sodium bicarbonate,
which is baking soda.
This is about 4-5 tablespoons worth.
Add it into your vinegar with lots of stirring.
This is rather boring so we'll just speed it up for ya.
When you do it go slowly, don't let it overflow, and let it settle down before adding more.
What we're doing is reacting the acetic acid inside the vinegar
with the sodium bicarbonate to create sodium acetate,
and generate carbon dioxide as a by-product.
Here we are, this is a weak solution of sodium acetate.
But it's useless for doing the hot ice experiments because it contains too much water.
So you want to remove about 90% of the water by boiling it down.
This will concentrate your sodium acetate to the level you need.
This took us about three hours so we're going to skip over that part.
So from one liter we boiled down to about 100-150mL of water.
This is sodium acetate and it's at the right concentration for the hot ice experiments.
Don't worry if your solution is a little yellow or brown like ours, this is not a problem.
Once it's ready, take it off heating, and let it cool down to room temperature.
Ok, let's make our sodium acetate freeze.
Let me try and pour it here....
Oh... Crap....
Looks like i was too slow in pouring it.
I'll have to remelt this.
Ok, but as you can see we got ourselves some pretty good sodium acetate.
I'm going to have to find a smaller beaker so i can handle it better...
Ok, we're back, I've put the stuff in a smaller beaker and remelted it.
Now it's cool and we're going to recrystalize it by dropping in a few solid crystals of sodium acetate.
There you go, with just vinegar, and baking soda, and a stove, we made sodium acetate.

Oh yeah, a quick tip if you are having trouble
cooling off your stuff before it freezes.
While it's still hot put a covering on it.
This will keep the humidity in
and prevent drying on the sides that results in premature freezing.
