But a Brazilian researcher, who also happens to be a banana lover, has taken an interest in the lowly banana peel and is helping to remake its image. The banana peel, it turns out, can take water dirtied by heavy metals from mining operations or other activities and turn it to clean drinking water.
Magic? No, actually, it's chemistry. Gustavo Castro is an environmental chemist at São Paulo State University who says he'd heard for a long time that the peel of the banana was the best part of the fruit, where most of the nutrients and proteins reside. So he decided to investigate its chemical composition to see if these banana peel boosters were right, he told the American Chemical Society in a podcast.
What he found was that banana peels contain nitrogen, sulfur and organic compounds such as carboxylic acids. Castro was especially pleased to find these acids because they can bind with positively charged metals that leach into rivers from industrial operations.
To test the peels, Castro and his colleagues chopped up and dried a bunch of them and mixed them with water from Brazil's Paraná River, which was polluted with copper and lead. The peels performed as well or better than many typical filtering materials, like silica or carbon. What's more, the peels are a cheap waste material. Castro found they could be used up to 11 times before they stopped working as purifiers.
The findings were published earlier this year in the journal Industrial & Engineering Chemistry Research, a publication of the American Chemical Society.
Of course, with any brave new idea there's always a word of caution. The banana peel can't get rid of bacteria in water, so don't strap one around your faucet just yet.

In other news, I just recently saw the music video for the following song and now can't get out of my head. It makes me think about things I'd sometimes rather be able to ignore.

Yowza! What's next? Posting in forums outside of the Off Topics?!

Quirk's post also brings up a good idea---going back to noteworthy-ish pages, and grabbing some posts others have mentioned about you. (Remember, you can go to any page by clicking on the 'Page 1 of 3988' link )

Anyone wanna talk about the Iran situation? or have a lively discussion about...i dunno....movies or something?
I guess it was only a matter of time before we'd start talking about "the good old days" of the thread, back when we were young and easy, when candy tasted sweeter, and we hadn't become mature and jaded. Like remember page 17? Oh, those were good times...boy, some of the crazy things we did back then...if only we could recapture that time... **adjusts position in chair, becomes keenly aware of arthritis and gout in doing so [homage to Andy]**
I haven't seen many movies about Iran. Was Not Without My Daughter set there?
It's no Tombstone, but we could bounce some Big Lebowski quotes around...
