My chemistry teacher warned me to stay away from people who would use the ° sign for Kelvin ("90°K") or leave it out when talking about degrees centigrade ("-180C")... this guy does both ;-)
But it wasn’t always so. From https://en.wikipedia.org/wiki/Kelvin
> In 1967/1968, Resolution 3 of the 13th CGPM renamed the unit increment of thermodynamic temperature "kelvin", symbol K, replacing "degree Kelvin", symbol °K.
And from Lord Kelvin himself in his "On an Absolute Thermometric Scale", a copy of which is at https://web.archive.org/web/20080201095927/http://zapatopi.n...
> The characteristic property of the scale which I now propose is, that all degrees have the same value; that is, that a unit of heat descending from a body A at the temperature T° of this scale, to a body B at the temperature (T-1)°, would give out the same mechanical effect, whatever be the number T. This may justly be termed an absolute scale, since its characteristic is quite independent of the physical properties of any specific substance.
So even Lord Kelvin himself was originally speaking of degrees in his absolute scale.

This sounds very nearly almost as toxic as dihydrogen monoxide- a truly deadly substance[0] that must be used very carefully. [0] https://www.lockhaven.edu/~dsimanek/dhmo.htm [Edit] tough crowd tonight.
Funny joke if you're 12. Which I guess is why everyone heard it from their middle-school chemistry teacher.
Following a link in the comments gets you to the PDF of Streng's 1962 paper, with some good notes. Having a Pyrex cylinder of this stuff sitting in anything other than a cryostat 20 miles from civilization sounds like a very bad idea. https://www.andrew.cmu.edu/user/jklein2/O2F2.pdf If I wanted to synthesize this stuff, I think my preferred method would be SCP-294 https://scp-wiki.wikidot.com/scp-294
I'm curious as to what a "safe distance" is when requesting a cup of anti-water. Reacting 8 ounces of antimatter with a similar amount of matter releases energy on the order of a large thermonuclear bomb.
My personal favorite article from Derek Lowe about a chemical that isn't actually all that dangerous... but you still likely don't want it around. https://www.science.org/content/blog-post/things-i-won-t-wor...
