Unfortunately, I don't have a photo of the end result! (Lost it)
But I can say that the experiment was a success and our flowers changed colours to match the different coloured liquids!
Three recent experiments - mostly relating to needle felted jewelry ideas.
I've been toying with the idea of doing a steampunk necklace and having seen that octopi often show up in steampunk I made one. Flat on the back, dimensional in front. Doubt that this particular piece will work with the gears I bought.
Beads and a Cabochon - I've used silk before with my Merino fiber and I know that it adds a luster and reflective quality that the wool lacks. The beads and cabochon are very firmly felted.

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
On the right ~15mL of calcined garden gypsum (rinsed) was combined with 7.5mL of a boiling solution containing sodium chloride, sodium carbonate and uranyl nitrate in an aluminum form. The mixture released much gas (CO2 ?).
On the left ~15mL of DAP Plaster of Paris (containing CaCO3) was combined with 7.5mL of the cooled previously mentioned solution after it had been treated with HCl to remove the carbonate ions. The still acidic solution reacted with the CaCO3 in the Plaster of Paris mix and was mostly neutralized by the CaCO3 becoming CaCl2 and CO2 gas (and H2O). The mixture was left to set in a plastic form.

Much appreciation to Gordon Czop for the uranyl nitrate.

Zinc chloride from pennies and calcium chloride from limestone (digested by muriatic acid) was combined with sulfur, NaCl and 3 drops of MnSO4 sol. This was melted with a MAP gas torch.

First Appearance - Batman: Shadow of the Bat #3 (Aug. 1992)
Amygdala is the alias of Aaron Helzinger, who is a sometime opponent of Batman. He has reduced mental capacity, is prone to outbursts of violence and has super-strength due to medical experimentation on his brain, chiefly the removal of his amygdala- the bundle of nerve cells in the brain that control emotional associations of many kinds.
Helzinger's amygdala cluster was removed in an attempt to cure him of his homicidal rage.This procedure resulted in Amygdala becoming exceedingly angry and was the opposite of what the surgery was supposed to achieve. Easily led due to his childlike nature, Amygdala has been the pawn of a number of Batman villains, but when properly medicated, he can be peaceful.
In this experiment, the color of the liquid in the flasks will change to yellow if you blow in the straw. This student tests whether an aquarium bubbler will also cause the color change. For more science experiment ideas, see www.biologycorner.com
Matthias working on the "Touching Surfaces" experiment by DLR. He posted these images to his social media on 26 November with the caption:
Please touch 👇 What looks like a triple fingerprint sensor is the @dlr.en "Touching Surfaces" experiment. It consists of differently structured touch panels made of steel, copper and brass, and every time I leave my fingerprint I also transfer my own microorganisms Scientists on the ground can analyse where the microbes accumulate and develop new types of antimicrobial surfaces.

so I discovered that you can use an oil pastel as a resist. even cooler is that you can scrape off the oil pastel to reveal the color underneath. eyes and mouth were done this way. i then went back and added outlines with sharpie.
With the wig frustrations I've had with my Puki, I try something I read Spampy do. I've done this before with my tinier elfdoll but directly to a spare head cap. I didn't think it would work - peeling the plastic wrap off from the inside but it works. My top isn't great but this is the first time my Puki has had a wig that fit and fit her face.
No worries, you wig makers - No way would I try to sell these - you guys make amazing wigs and I have enough to do and I'm betting these fall apart with a good dose of water. The mohair I use is also for cloth dolls and such, nowhere near the quality mohair wig makers use so cutting hair from it isn't painful at all.

Uranyl nitrate solution was used to hydrate 15mL of DAP Plaster of Paris mix. The result showed hardly any green uranyl fluorescence, what could be seen was yellowish green. The plaster was then rehydrated using a concentrated sodium carbonate solution. The water was evaporated and the mixture was then calcined at ~150 degC for 4 hours in an oven. It was then rehydrated using a sodium carbonate solution. The plaster mix bubbled for about a half hour releasing much CO2 gas. After drying a coating of yellowish crystals formed on the surface.

Connectivity and readymade.
Experimenting, manipulating and combining daily life objects in order to attempt, to force or to mystify a workable connection between them, at least to make it visible and/or possible. This exercise is to be considered as a warm-up, a first step towards a further installation or project.
