Experimenting with water drops. Took these earlier on, my first batch of them, and is also my first attempt at them too.

Since reading the book Zero History by William Gibson I've been paying more attention to fashion.
Recently I've started observing fashion actively. I'm only a beginner without knowledge and without a frame of reference. So the easiest way to start was to observe outliers. Establish a subjective baseline by looking at the crowd and then record anything that is different.

18 Watt Triple Output UV lamp from Polman Minerals - Way Too Cool UV lamps
I was recycling some old micro-vial containers at work the other day, and it occurred to me that all those little squares would look neat filled with color. So I took one home to see what I could do with it. I'd planned on using food coloring, but couldn't find any, so I used gelatin mix combined with vinegar (I had a vague theory that the vinegar would make it brighter somehow). I got the color into the squares with disposable pipettes.
It wasn't all I'd hoped for, but it kept me amused for an hour...
Penelope has been acting weird every time I work on a doll. She shakes like crazy. I wanted to see how she would be if my attention was focused on both her and a doll. She was fine. No shaking. I guess it's just when my attention is totally focused on the doll, she gets nervous and shakes.
Or she's so afraid of Icy doll Beatrice that she can't even shake!!

Trying another experiment Colour popping this time , I didn't know wether to colour all the flowers in but as the 1st one took me ages i thought i would leave it as it is for now
Errol Korn, lower left, explains the dropsonde experiment to Janel Thomas, a University of Maryland Baltimore County (UMBC) graduate student, seated, as Bob Pasken, standing left, and Jeff Halverson, a GRIP project scientist from UMBC, look on inside NASA's DC-8 airplane, at Fort Lauderdale International Airport in Fort Lauderdale, Fla., Sunday, Aug. 15, 2010. The Genesis and Rapid Intensification Processes (GRIP) experiment is a NASA Earth science field experiment in 2010 that is being conducted to better understand how tropical storms form and develop into major hurricanes.

Experiment in Color ?
Color shifts to bring out the positive image. The "Cafe" sign looks good but those are no where near the correct colors.
Morgan Utah Oct 2022. Fuji F-250 shot at ISO 200. Nikon F4 with Nikkor kit lens. I shot these to experiment with a 1948 reversal formula from Lars Moen. Lars said try Kodak Dk-20 as a first developer to balance the tungsten, and then he had a simple color developer:
Sodium Bisulfite 1g
Color Developer 4g
Sodium Carbonate 67.5g
Potassium Bromide 2.5g
all in a liter of water.
I substituted 5g of CD-3 as the color developer.
Normal DK-20 dev time in 20c water is 15 minutes, so I did that. pH of the color dev was 10.34 so I raised that to 10.6 with potassium hydroxide. Suggested time was 15 min at 20c.
I use dnormal pot fer bleach for 5 minutes and fixed for 5 minutes with Ammonium Thiosulfate fixer.
Somehow the negative is partially reversed. I noted later that he said use the DK-20 for 25 minutes at 68 degrees. Sounds like A LONG TIME. But next time I'll try that. The negatives are dark but only lightly exposed, so the first dev is probably speeding up the emulsion, I'll bracket some shots and see what happens next time. My instinct is to shorten 1st developer but I'm game to try 25 minutes.
Although it isn't what I was looking for, I love the effects. The rest of the roll to follow.
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.

Uranyl with carbonate (FL Blue-green >BL/UVabc)

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.
