While I do appreciate the sentiment, thanks, but no thanks. I neither deserve nor desire such a thing. There are many others who do deserve them.
Oh, physics, absolutely. It’s the science which underpins all the others and provides the framework for our understanding from everything from aardvarks to zeppelins.
Why do spit-out sunflower seed shells turn green when left out for a couple of minutes.? This happens for one of my kids, but I’ve never seen it happen for anyone else. I would presume that there is something in her saliva that reacts to the shells, then oxidizes, but I have absolutely no idea what.
Fisha, I have no idea, but whenever the color green is associated with plant-based foods, the first thing I think of is chlorophyll. I found this, which provides something of a clue, even if it’s not a concrete answer:
Who is your favorite fiction writer? What is your favorite fiction book? Who is your favorite non-fiction writer? What is your favorite non-fiction book?
Q.E.D.: Well, I found out something which may be connected to both the biscotti & the sunflower seed thing.
There is a litmus test which involves red cabbage juice. The juice contains anthocyanins, which turn green in the presence of a base. Grapes have them too. The primary constituent of anise/fennel is sulphur; I don’t know its pH but I’ll bet that’s what does it. Either that, or the baking soda in the biscotti.
Sunflower seeds, I don’t know; but there are anthocyanins in cornflowers as well, apparently, and it’s not too far of a leap to sunflowers. If this is the case, it would suggest that fisha’s daughter has a somewhat base body pH; if I’m not mistaken, that would put her ahead of the game, health-wise. Acidosis is no joke.
Anyway, cite:
Oh, and thank you, Q.E.D. and bbs2k. I just love scientists!
