You can find absolute zero experimentally by taking a fixed amount of gas and measuring it's volume at different temperatures while keeping the pressure fixed. It makes use of the ideal gas law (pv=nRT) or Charles's Law.

10:59 one bottle for calculating absolute zero, another bottle for reading the comments after the video goes up.

You know, I am a bit of a scientist myself. I remember that time I used vodka and got to the point when I stopped moving or even jiggling about.

I'm so glad you didn't get -273.128 or something like that. So many videos make it seem like the first go was perfect, but I love how you explained your experimental errors, tried to rectify it etc. Otherwise future potential scientists might feel put down when their experiments doesn't work out 100%

great choice, vodka has been helping people achieve absolute 0 on the scale of dignity for ages

"No such thing as negative jiggle" you've never seen me dance. Well, attempt to dance.

Steve, love your nerdy videos - you’re basically fitting a line: y = ax + b using two points which gives you both a and b, thus a graph would have helped the explanation.

I did something like this at Physics A-Level, I got 0K=-600°C 😭

"There's no such thing as negative jiggle." This is my new favorite phrase. I need this on a t-shirt with the lattice of molecules and Steve's face to go with it.

"...if you're trying to work out something for yourself, it's really helpful if someone else has done a much better job".
Words to live by.😁

When your wife finds your Vodka bong and you have to devise a story that it's all for "an experiment"

I can just imagine the huge grin on Steve's face when he went to the bottle shop to purchase some vodka for this experiment and saw the bottle of Absolut Vodka.

"There are a number of ways to improve this experiment"
Yeah, drink the vodka.

I love this as it goes through the trial, error and improvements that people can make in experiments.

So -297 C is Absolute Zero on the Parker scale, also known as Parker Zero

That was the best definition of a vpn that I ever heard.

Great video, thanks!
I didn't read the 1.7k comments above, so it may discussed earlier.
However, another problem in the 1st experiment was the different head of vodka between the two temperatures, causing the pressure not to be constant.

1) OK, so I didn't know there was such a thing as "absolute hot" or Plank Temperature. Interesting! 2) There's a typo in the footnote. It should read "trippple point of watter".
