The pic is blurry but it's easy to see how intense the rain was: the rainbow extended below the ground, as there was enough mist on the windshield to continue the bow.

That just means that the pot of gold was buried as opposed to sitting on top of the ground (as it usually is).

Thanks


Thank you volatile... I'm working on retrieving some pretty okay pictures of when i did experiments with dyes i hope to have then on the blog soon.

great! I've always loved dyes work. Been reading one of the articles in sciencemadness library on them. What were you working on? I've been doing some theorizing myself on some procedures.

Actually I'm not working on dyes specifically it was just an interest I'd developed after I got access to some fluorescein. However, I do hope in the future to once again dive back into dye chemistry, to be more specific though, more into fluorescent dyes and glow stick preparations. Synthesizing organic fluorescent dyes and seeing how they behave when substituted as the main fluorescers in glow stick reactions. As well since this thread is about pretty pictures here are the latest pictures used from my old experiment collection, just posted on www.lab-chemist.tumblr.com

Preparation of crude eosin dye by bromination of fluorescein...

Sure! Those look great! Do they happen to fluoresce at all...?

That reddish-brown gunk is washed out with a little cold methanol and I will soon have some white crystals at the top of the funnel :D

Yes Volatile, the crude eosin dye did fluoresce, well under the same conditions used for the fluorescein. However the colour was a deep red and I couldn't get a good show of the colours with my camera so I don't really have a good picture to show, but this is what I did capture though...

Nice! Wonderful pictures! Have you considered contributing to sciencemadness wiki (the link's in my sig)? Some of your procedures would be nice to have on there!

Cool. What colour is the liquid? If it's blue, doesn't that mean that it's N2O3?

Apart from nitric acid, copper metal won't react with most acids unless there is an oxidizer present(hence the H2O2). I have a single crystal of CuSO4 that I've been growing for a while; it's bigger than the end of my thumb now.

Conc. boiling H2SO4 and copper do react but in a different way. Has anybody tried this?

Yes but I was more trying to ask if anybody has actually tried it because it sounds like a nice experiment if anybody could tell me about procedures and such.

I was trying to figure out how this strange cloud formed with wisps going out on either side of it. There's an airplane off to the left of it for size.

Hi Jylliana!
Welcome to SM!
Hope you enjoy using the site! If you have any questions, U2U (kinda like PM-ing) someone. Nice picture, too!
I must comment, glad to see you are on the site! There are not very many females that are interested in chemistry, let alone state their gender.
Regardless of stereotypes, enjoy the site. Is there anything about chemistry you are particularly interested in? Specific branches?

-Nathan, The Volatile Chemist
