Which type of juice cleans pennies the best?





2003

I have posted many questions over the past few months hoping to get so answers to my questions and research, but I haven't been getting any answers to my questions. I need this information by Thursday for my science fair project or I will get a failing grade for this semester. I can't afford to do that because there will be no summer school. PLEASE HELP ME! I NEED THIS INFORMATION AND R-E-S-E-A-R-C-H! ---------------

While I never recall doing this project in school, it apparently is quite a popular experiment these days. But one has to wonder.. are today's teachers not fully explaining the experiment, or not properly explaining the chemical reactions between acids/bases and metals? Or.. are the students nowadays just used to doing an internet search, and cutting and pasting the answers. Jerrica, your last word in your question was RESEARCH, which means, you are to do the experiment, document your results, RESEARCH the properties of each juice, and write your conclusion.

tomato juice, orange juice, grape fruit juice, lemon juice, lime juice,and pickle juice all work really good. I tried it and got an a+ on my science project.

I want to know some research about my project because my teacher told me and the other kids that did not do other research about it need to bring it in the next day.

From what you've read on this page and the FAQ we referred you to, what is your tentative conclusion, Jasmine. And, having read the FAQ, you should be able to phrase the question more precisely now than 'cleans a penny best'. After you have finished your experiment, please post what you found out about cleaning pennies.
