okay on a different trail of thought today and i just had to share this one with you because it fascinates me and i am sure it will you also it is possibly one of the most amazing photos i have ever seen not because of scale or majesty or any historical moment nope and nope again this one is quite the opposite in this one we are looking toward the tiny and higly detailed
now i have tried to include the picture as large as i could go so you could see the detail
these tiny hair like structures are actually frost i shall try and find some proper background for you:
Where does hair ice form? In the three cases I found that morning, all were on about 1-3″ diameter logs; all were near the ground or other wet objects; all were growing on bark-free regions and growing partly downward. Also, the region was quite soggy. Three days later, also after a fast freeze, I saw hair ice in the same place.
I saw some other hair ice nearby. Although this looks like a lot of water to be coming out of the wood, there actually is relatively little water. After scooping up about a cup and a half of the stuff, I found that it melted down to a little less than a tablespoon. That is, the water essentially expanded about 30 times to produce the hair.
So, how does this ice grow, and what pushes it out?
The hair ice forms like the ground needles that make the ground crunchy. It may not be exactly the same, but I think the basic processes are the same. Ground needles form when the top of the ground starts to freeze, but the ice cannot penetrate the fine pores in the soil below. But the fine pores allow melt (liquid water) to flow up to the ice.
The basic theory for ground needles is from Stephen Taber in the 1930s, and I sketch it on the upper left in the image below. After a little ice forms on the ground surface, a thin film of water will remain between the ice and the soil grains beneath.
As the ice starts growing down between the pores of the soil, the ice surface must curve. But the surface tension of the ice effectively stops the growth. Capillary forces draw water up from below, the water freezes below the ice needle, which decreases the film thickness, increasing the pressure, and pushing the ice up.
The same process basically acts to push the hair ice outward from the wood, as shown at the upper right in the sketch.
to give you some kind of idea of scale the main big picture is taken of a piece of wood measuring around 2.5 cms i tried to get it as large as i could so you could see the beautiful hair like structures but for those who want to go looking for this stuff here is another picture to show you what you are looking for
so there you go nature damned amazing isn’t it ^_^
have a super sunday everyone
love and peace be with you all
