I saw it on the web recently, a photo documented explanation demonstration of why cleaning pennies with vinegar and salt worked the best . There were at least 7 photographs, before and after pictures, very nicely composed. I'm trying to show my students how to make a great visual presentation of their experiments, using the high tech tool of their digital cameras. I can't find that web page now, and failed to fbook mark it. Help me find a quasi professional presentation, of this chemistry experiment, explanation. copper oxide, vinegar, salt, cleaning, are all key words. The explantation should also have a few chemistry oriented formulas, etc.

You're the instructor, why not take digital photos yourself of all the steps. Then put together your presentation including all the stuff you asked us to find for you.
If you can't do it well, why are you asking your students to do it from a copied presentation?
