liquid-mercury

This is Winifred, my sourdough starter. I just fed and cleaned her home. 

For those involved in kitchen witchery, I strongly recommend keeping a sourdough starter. It’s far easier than it seems and when properly cared for it can live for centuries. My relationship with my mother starter is like that of a domestic familiar who keeps the pantry stocked and the home harmonious. Bread made from my consecrated starter creates sacred bread for my rituals and offerings. I also use its sour liquid as a potent mercurial spell ingredient.

I’d really like to see people’s ideas of using sourdough in a magical context! There’s so much potential!

One of mercury's cool properties!

Did you know that a human can float on top of a pool of liquid mercury? Some of you science peeps are probably saying, “DUH, it’s extremely dense and a ‘heavy’ metal!”, but did you know that people actually did this? The photo of the miner below is from a 1972 issue of National Geographic, back before people realized that sitting on top of a giant pool of liquid mercury, as it continuously vaporized and you inhaled it, was not very good for your health. 

How I found this photo: from Theodore Gray’s website - a man who collects samples of all the elements in the periodic table, even the poisonous ones.

Liquid Mercury Discovered Beneath Teotihuacan Pyramid

(Source)

“MEXICO CITY, MEXICO—“Large quantities” of liquid mercury have been discovered in a chamber at the end of a tunnel located beneath the Pyramid of the Feathered Serpent in Teotihuacan. “It’s something that completely surprised us,” archaeologist Sergio Gómez of Mexico’s National Institute of Anthropology and History told Reuters.

Last year he annouced that three chambers had been found at the end of the tunnel, which had been sealed for 1,800 years. Jade statues, jaguar remains, a box filled with carved shells and rubber balls, metallic spheres dubbed “disco balls,” and pyrite mirrors have also been uncovered. The mercury could indicate that Gómez and his team are closing in on the first royal tomb to be found in Teotihuacan. He thinks that the mercury could have symbolized an underworld river or lake. If there is a tomb, it could help scholars determine how the city was ruled.“

Tabulaa - Bucket List - The Bean, Chicago
https://tabulaa.com/vitae/see_the_bean

Cloud Gate, referred to by locals as “The Bean”, for obvious reasons,is a public sculpture by talented British artist Anish Kapoor in Chicago, Illinois.

Cloud Gate, a public sculpture by Indian-born British artist Anish Kapoor, is the centerpiece of the AT&T Plaza in Millennium Park within the Loop community area of Chicago, Illinois, United States. The sculpture and AT&T Plaza are located on top of Park Grill, between the Chase Promenade and McCormick Tribune Plaza & Ice Rink. 

Constructed between 2004 and 2006, the sculpture is nicknamed “The Bean” because of its bean-like shape. Made up of 168 stainless steel plates welded together, its highly polished exterior has no visible seams. It is 33 by 66 by 42 feet, and weighs 110 short tons. 

Said to have been inspired by liquid mercury,the sculpture’s surface reflects and distorts the city’s skyline. Visitors are able to walk around and under Cloud Gate’s 12-foot high arch. On the underside is the “omphalos” (Greek for “navel”), a concave chamber that warps and multiplies reflections. The sculpture builds upon many of Kapoor’s artistic themes, and is popular with tourists as a photo-taking opportunity for its unique reflective properties.

So my science teacher told me that the Mad Hatter is mad because when hat makers would paint on liquid mercury as designs for their hats they would lick the paint brush so the mercury would stick to the brush and eventually the mercury would drive them insane and I thought that was really cool. I don’t know if it’s true or not but it’s sounds reasonable  

These golden lines reveal the complexity of turbulent convective flow. They come from a numerical simulation of turbulent Rayleigh-Benard convection, a situation in which fluid trapped between two plates is heated from below and cooled from above. This situation would typically create convection cells similar to those seen in clouds or when cooking. Inside these cells, warm fluid rises to the top, cools, and sinks down along the sides. With large enough temperature differences, instabilities will occur and cause the flow to become turbulent so that the clear structure of convection cells breaks down into something more chaotic. Such is the case in this simulation. This visualization shows skin friction on the bottom (heated) plate in a flow of turbulently convecting liquid mercury. The bright lines are areas with large velocity changes at the wall, an indication of high shear stress and vigorous convective flow. (Image credit: J. Scheel et al.; via Gizmodo)
