I know the Harlem Shake was a fad many would like to forget, but these stills were from the first video version of it that I saw and I thought it was pretty cool the Norwegian Army had a pretty sweet sense of humor about it.
One of the comments on the video is on point. I miss that era of the internet. It seemed so much more innocent, peaceful and heartwarming than it is now. 😞
It was a crazy time. I was pretty big into EDM, and so when I was in the field with the Marines and my company decides they’re going to do a Harlem Shake video with 150 dudes, needless to say it felt a little surreal. It was rare we got to act like goofballs, but for like one minute on the shores of Morocco we got to be absolute morons. And then we didn’t.
When you keep water still and cool it to below a few degrees below freezing point, it stays as water but when you give a physical shock to it, it freezes over! Like getting a bunch of Harlem shaking soliders in line.
H2O molecules can be in several different states at 0°C. The first picture depicts ice at 0°C, but you can also have water and water vapour at 0°C too.
Water vapour isn’t really applicable here, unless you’re talking about very low pressures. Although you could consider it a component in a mixed gas, it’s not really gaseous water. The true gaseous form of water is steam. Water vapour is more like water that has been dissolved in the atmosphere.
By analogy: sugar is solid at room temperature. But you can dissolve it in water. Have you converted the sugar into a liquid? No. Because sugar is a liquid only at temperatures above 160°C. But the resulting mixture is liquid.
Agreed that vapour doesn’t really play in to this, but I knew if I didn’t mention it someone would come in and ‘correct’ me. So I included it, and someone still came in and ‘corrected’ me.
My main point, that I didn’t make very well, is that I wanted to ‘correct’ the meme that both ice and liquid water can be at 0°C.
Man, this made me realize that “flash in the pan memes” used to be so much longer lived than they are now. Nowadays something mega viral has a half life on the order of days but also has much more segmented awareness/spread
Sort of. The triple point doesn’t really exist at standard atmospheric pressure. The true triple point is somewhere around 600Pa pressure – or a out 0.6% of atmospheric pressure. You can achieve this in the upper atmosphere, on Mars, or in a vacuum chamber where you pull the pressure down to that point.
There is such a thing as vapour pressure in our atmosphere which is different than the triple point. You see this as humidity. But this isn’t truly gaseous water – rather it is more akin to liquid water molecules held in a gaseous solution (the atmosphere being the solvent).
