like but in a bread form, that could be eaten without utensils or waterproof containers w/o compromising its nutritional completeness.
First i made a diy baking powder premix by mixing 12g of flour, 3.5g of citric acid and 5g of baking soda together.
The journal entries of actual baking follow:
* oiled a ~150ml glass, 32g flour, 845mg diy baking powder, mixed, 12g sunflower oil added, 14g ~20C water added, mixed, nuked for 90s, looks bubbling and unready, nuked for 30s more, looks strange, cut it open, seems not very porous, probably due to gas escaping instead of foaming (lack of egg?), tastes tolerable and like a shortcrust pastry
* not re-oiled the glass, 38g flour, 785mg diy baking powder, mixed, 8g sunflower oil added, 19g water added, mixed, 5g more water added, mixed, seems like oil is very unevenly distributed, nuked for 4min @50%, looks not much bigger than the first one, cut it open, has huge voids and dense regions inside but overall is softer than the first one; probably i should spend more effort mixing the baking powder with the flour
* not re-oiled the glass, 37g flour, 903mg diy baking powder, mixed with a teaspoon in a cordless drill, 25g water and 5g oil added, mixed, nuked for 4min @50%, the size didn't change, cut it open, the voids are less pronounced but dense regions are still very pronounced, seems softer than the second one; cut two dense regions and put them into hot water, observed some fizzling, probably i should mix the water in much more thoroughly
* not re-oiled the glass, 48g flour, 1015mg diy baking powder, mixed with a teaspoon in a cordless drill, added 25g 35C water and 8g oil, mixed with a teaspoon in a cordless drill, worked out poorly as the dough stuck to the "shaft" too well, and the flour at the bottom didn't get pretty much any water, added 18g more water and mixed manually, certainly too much water now, but the dough is still clumpy after thourough manual mixing with a spoon, nuked for 4min @50% at the center of the rotating dish, the result is wettish and the corners of the bottom failed to make it out of the glass intact, but it's soft while still keeping its shape well and doesn't seem like having any annoyingly dense regions
The results are: tinystash.undef.im
They aren't quite stellar, foaminess-wise. I've only dealt with commercial cake premixes with eggs before, and they worked out fine with similarily short exposures to microwaves; i think eggs help with foaming a lot, not sure how to replicate this w/o animal or poorly accessible products. Fatty acids? Agar? Some other surfactants/hydrogels?
Made a few experiments baking minimalistic quick wheat bread in a microwave oven, in the hope that the discovered technology would allow me to produce something First i made a diy baking powder premix by mixing 12g of flour, 3.5g of citric acid and 5g of baking soda together.

Просматривал здесь (http://chemistry-chemists.com/Uchebniki.html) учебники (там кстати классный список "Книги для юных химиков": Химия для любознательных, Опыты без взрывов, Чудеса на выбор). Сначала хотел читать совсем школьное, но университетские учебники внешне выглядят доступно, боюсь только квантовости. Анорганикум, Гринвуд — ня. Однако почти нигде нет задач — отдельные сборники задач и задачи с межнаров это конечно круто, но хотелось бы обычный учебник с задачами на закрепление, возможно сложными. Кроме того, это всё старые учебники, составители кажется специально ничего нового не включали, и в списке только русскоязычное. Жуйк, посоветуй что-нибудь современное годное, английское или русское, с задачами. Я пока остановился на Principles of Modern Chemistry.
Список крутых химических каналов на youtube:
youtube.com some great home chem expts and enviable glassware
youtube.com — more great home expts
youtube.com — many great home expts and syntheses
youtube.com — home chem
youtube.com — chick with interest in medical/chem/radiation etc
youtube.com — chem very high power lasers high voltage / x-rays — some really dangerous expts too
youtube.com — expts and demonstrations
youtube.com — some good simple expts, where to get some chemicals, reviews of other channels. sadly the guy's voice makes me want to hurt myself.
youtube.com Конечно, динамику в реальном времени он не всегда тянет, но представление о силах связей можно получить тактильно.
Киллер-фича молекеулярного редактора Avogadro — интерактивная оптимизация молекул. Потом я скачал оригинал, 6-е издание, 1120 страниц.
У этой книжки есть свой сайтец, где есть куча флешек на тему, есть quiz`ы, и вообще всё уберняшно.
В рашке такого не будет никогда, ящитаю.
bkchem.zirael.org наиболее удобен оказался из того, что у нас есть открытое и c ебилдами. Есть, правда, ещё несколько хороших рисовалок, в том числе и на яве, но ебилдов нет, может позже ещё раз пересмотрю и напишу ебилд к приглянувшейся.
вроде с рисованием молекул освоился, bkchem
