10 月 14 日把紅茶菌移到新的大玻璃罐，大約三公升左右。
過兩天左右表面就已經形成一層薄薄的膜，紅茶裡面有些白色霧狀的東西在漂浮。
On OCT 14th, I moved my Kombucha to a new glass jar around 3L.
A light skin formed on the surface of black tea after two days, and there are some white, foggy stuffs floating in the liquid.

many has tried to make it waterproof before, but seems like no natural and DIY solutions yet: https://publiclab.org/questions/lait422/04-23-2018/how-can-i-waterproof-kombucha-leather

only this works but its not natural

10月26日我也把紅茶菌換盆了，準備了三公升紅茶混合之前的全部菌液，但新盆子太大，先觀望幾天。
I've moved my kombucha to it's new home the 26th Oct. I prepared 3 liter black tea but it seems not enough for the box...I'll see how it grow.


另外之前在中心藍染的紅茶菌相當美麗～（謝謝筱翎幫忙拍染色照！）
Besides, this kombucha sample dyed with indigo is very good looking! (Thank you Hsiaoling for the photo!)

Kombucha Leather Tryouts

Also wanne go more into the kombucha leather production as well. So far what I have been using to make my kombuha hydrophobic was shellac or bees wax which is locally available her. mmmh shellack is not (https://en.wikipedia.org/wiki/Shellac) but the locals here use it for carneval mask production

Shelllack has good properties, still testing about the surface and felxibility condition and how long it is lasting in a good condition. I have three different approaches tested out.
- Glycerin --> stays soft, feels humid but is not, is not water repellant
- shellack --> makes a shiny water repellant surface.
- glycerin and shellac --> flexible more soft and water repellant.

I have been experimenting with it and it so far is not bad, both the bees wax and the shellack. Bees wax is quit modular on the surface structure, in means with applied heat will be possible to modulate the texture of the surface. Using bees wax is inspired by the zero-wast wrapping foil: https://www.beeswrap.com/ and its a local product.

I am now testing to imbody flexible circuits into two layers of kombucha and see if we can fuse another dried kombucha leather, sandwiche layer by melting them together with rewetten the kombucha.

here also simple play around with kombucha leather and leftover SND-Electronics

KOMBUCHA - Artists and designers are exploring the potential of microbial leather as bacterial cellulose film and a sustainable alternative to the ethically and environmentally problematic use of animal-sourced leather. Kombucha Green Tea a health promoting fermented beverage traditionally made by fermenting a sweetened green tea with a symbiotic culture of yeast species and acetic acid bacteria. Bacterial cellulose film also called biofilm, drives new promising hopes to scientists designers and food enthusiast. It has been vividly discussed as a material source for further research not only into textile but also for medical purpose. Because it has well-defined functional products and is maintained easily at the laboratory-scale, kombucha has potential as a mixed-microbial model system.

I found this interesting, “we are of the soil”, an idea given by this book “Farmacology”.
bacteria can be transported by our food, by this connection, what we eat and drink can affect the bacteria composition in our gut, and there’s a lot of impact from it. Many research shows that our personality, choice, medical condition can all be affected by our gut. This book suggests a strong connection between farming and medicine. There’s poetic communication in it, by the language of bacteria.
我發現這很有趣，“我們是土壤”，這本農作物學書Farmacology給出了這個想法。
細菌可以通過我們的食物傳播，因此，我們的飲食會影響腸道中的細菌組成，並且產生影響。許多研究指出，我們的腸胃會影響我們的個性，選擇，醫療狀況。這本書暗示了農業與醫學之間的緊密聯繫。 通過細菌的語言，其中充滿詩意的交流。

What is Farmacology?
Farmacology is an invented word that combines Farming and Pharmacology. It is meant to capture the idea that a farm, at its best, can be the source of powerful medicine. The book Farmacology is an exploration into the many ways that our health is connected to the health of the farm. What I discover is that this connection happens on two levels: the art and science of farming offers us valuable farm-to-body health lessons and that the farm itself gives us a whole array of healing foods.
農學是結合農學和藥理學的發明字。它意在捕捉這樣的想法，即一個農場最好可以成為強大藥物的來源。 《農學》一書探討了我們的健康與農場健康之間的多種聯繫。我發現這種聯繫在兩個層面上發生：農業的藝術和科學為我們提供了寶貴的從農場到身體的健康課程，而農場本身為我們提供了多種保健食品。
What was the inspiration for this book?
As a doctor, I am always trying to practice in a more ecological way and to think of my patients as part of a complex ecosystem rather than as a series of organs with their own specific malfunctions and diagnoses. I have discovered that good farmers take this holistic approach since they are always fretting about the interaction between all the players in their ecosystem: soil, air, microbes, animals, humans, plants.
The more I learned about the science of farming, the more I recognized its connections to medicine. For example, did you know that our gut physiology actually mirrors what happens in the soil? The intricate nutrient exchange between soil, microbe and plant is like the dance that takes place in our intestine, involving the mucosal lining, resident microbes and food (plants and animals). The biochemical makeup of soil also roughly matches ours, with a similar nitrogen-to-carbon ratio and the same range for normal pH (6.0 to 7.5).
Finally I realized that carbon, nitrogen and every other mineral and vitamin building block in our body is derived from soil (via our food). In other words, we are not simply nourished by the soil; we are of the soil!
作為醫生，我一直在嘗試以更生態的方式進行練習，並將我的患者視為複雜生態系統的一部分，而不是一系列具有特定故障和診斷的器官。我發現優秀的農民採用這種整體方法，是因為他們總是為生態系統中所有參與者之間的互動而煩惱：土壤，空氣，微生物，動物，人，植物。

我對農業科學了解得越多，就越了解農業與醫學的聯繫。例如，您知道我們的腸道生理實際上反映了土壤中發生的情況嗎？土壤，微生物和植物之間複雜的營養交換就像在我們腸道中發生的舞蹈一樣，涉及粘膜襯裡，常駐微生物和食物（植物和動物）。土壤的生化組成也與我們的大致相符，氮碳比相似，正常pH值在6.0至7.5範圍內。

最終，我意識到我們體內的碳，氮以及所有其他礦物質和維生素的構成要素均來自土壤（通過我們的食物）。換句話說，我們不僅僅被土壤所養育，而是被土壤所養育。我們是土壤！
