This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
~15mL of DAP Plaster of Paris (containing CaCO3 and SiO2) was combined with 7.5mL of a NaUTC (sodium uranyl tri-carbonate) solution and allowed to set in a mold.

Image 2 of 4. These are acrylic beads, the kind used in aquariums and such. The four scenes are positioned exactly the same. I merely changed the lighting. You can see how different the view and details revealed by the changes. Random Stuff 039
I was bored tonight and decided to toy around with some shots from the SRT-10 shoot. This was the best one of the experiment imo.
For me, fashion is a form of art. I wanted to take the time and experiment with some styles and colors to se what works and what doesn’t. Feel free to comment on what styles you think work best 😃
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.

This experiment demonstrates the shift in color from yellow-green to blue-green in aqueous solutions of pyranine when made acidic.
The fluid from a yellow hi-liter pen was removed and mixed with water (shown in the center test tube). The left test tube contains that solution with 1 drop of muriatic acid added. The test tube on the right contains the solution with 5 drops of a sodium hydroxide solution.
The pH of the left test tube was ~1 and the right test tube ~14. It was hard to measure the pH of the solutions since it dyed the pH indicator paper yellow.
Upon adding the drop of acid to the pyranine solution, it changed from yellow green to clear. This was because the pyranine had been protonated (provided a hydrogen ion) which reduced the absorption of light at 450nm.
Refer to this article: www.ugcfrp.ac.in/images/userfiles/30241-CPL_399_147.pdf
"At a pH less than 7, the absorption spectrum of pyranine
(HPTS) exhibits a peak at 405 nm which is ascribed to
the protonated form (ROH) while at a pH greater than 7 the
absorption spectrum exhibits an additional band at
450 nm arising from the deprotonated form (RO)."

First time attempting to spray paint. I need lots more practice and some super thin caps! But it was fun.

This experiment demonstrates the shift in color from yellow-green to blue-green of minerals containing the uranyl ion in conjunction with carbonates.
Uranyl nitrate was combined with NaCl and recrystallized on the glass rod. Behind it is a specimen of meta-autunite from the Daybreak Mine in Spokane WA, USA. Meta-autunite is a uranyl phosphate mineral.
Uranyl nitrate solution (0.25M) was combined with a sodium carbonate solution (1.25M) and was used to rehydrate some DAP Plaster of Paris mix which was set in a square mold.
Initially (when still wet), there was no fluorescence but after the calcium sulfate re-hydrated (and the mix produced CO2? bubbles), the resulting plaster fluoresced a bright blue-green, typical of carbonate based uranyl minerals. Behind the plaster square is a specimen with a coating of andersonite from Yellow Cat Mesa in Grant County UT, USA. Andersonite is a hydrated sodium calcium uranyl carbonate.

My friends Teresa and Geza are very good at this kind of shot. Mine pales in comparison to theirs, but I just wanted something to post quick. :-)
This shit looks good on nearly all sizes, and it isn't too repetitive!
The code is 285kb for a fully textured grip!
I used Benjoo's ERGO grip as an example. Perhaps because I will use this in future builds :D

Last night I did some experimenting with Sparklers and Joss sticks, taking pictures of smoke, which turned out pretty cool.
I used my Yongnuo Speedlite 565 EX to create some backlight for it, so the smoke is visible.

Experimenting with long exposures. I need to figure out how to prevent the lens flare, more time behind the lens is needed.
Electrifying experiments in Belgrade's Tesla Museum (catch the lightning in the right moment ;-) with the camera
I'm really impressed by me*voila's magical work & have tried this.
Please view the photo from a real genius（＾ワ＾）.
I needed a break from some of the bigger projects I'm working on, so I spent the night playing with my Accuquilt cutter. This is the new Denyse Schmidt "Aunt Edna" and the super sweet Washi collection by Rashida Coleman-Hale. I'm thinking of appliquéing something in the center of the star and doing a little hand stitching too.

I'm experimenting with processing black and white printing paper as direct-positives. For more on the process, take a look at Cameradactyl's YouTube feed.

aka Brain Fart #2. Refer to Experiment #1 for an explanation. So I think compositionally the balance is a little out but I'm loving what's going on with the front of the building and tree. I'm thinking I might take this approach to some landscapes and see where it leads.
BR Research Department (Derby RTC) Class 24 No. 97201 Experiment: SLW catalogue No. 2406.
This is an example plucked from the middle of production and clearly vindicates our efforts to make a number of subtle enhancements to this 4mm scale model in the light of customer feedback and operational experience. Have a close look and see if you can spot the numerous upgrades…
It is worth mentioning that this RTC loco introduces a completely new period-accurate bodyshell (Crewe production series with late exhaust retaining the original cab front doors). We sincerely believe this representation will quickly establish itself as the definitive model of the now-preserved machine once railway modellers get them running on their layouts. Optional nameplate transfers included (shown applied).
