AboutDan Fink Expertise Though my experience is mostly in the fields of electricity, magnetism, and physics, I have a broad science background. My career is in the field of alternative power sources -- solar, wind, water and battery power. But any questions about electricity, magnetism, energy conservation, power generation, electric motors, and even general physics are very welcome--especially from kids. They ask the best questions of all! I pride myself in answering science questions accurately, with ideas for SAFE, easy experiments that kids can perform by themselves--and that let them prove the answers to their own satisfaction. I think science should be fun, and available to everyone, regardless of age.
Experience I have volunteered in our local public schools for 5 years. I currently make presentations at our schools about electricity and magnetism, with a focus on solar, wind, water and other alternative power sources. I try to demonstrate at our schools how easy it is to make electricity, with simple devices using spinning magnets and coils of wire--powered by wind, water, bicycles, gerbils...etc. And of course solar panels! I am the webmaster of Otherpower.com, an alternative energy website. I have lived 10 miles from the nearest power pole for 11 years--I make all my own electricity from scratch with sun, wind and water.

Question I need to find the ingredients for Coke and Tropicana OJ. Thanks a bunch! ASAP Please!
Answer Coke is well-known for having their "secret ingredients" recipe locked in a high-security vault....though they might let you know the basics for your science fair project --- sugar content, acidity, etc. Same for Tropicana, they'll let you know the basics. Both these are large companies and answer such inquiries from students all the time. http://www.coca-cola.com
and http://www.tropicana.com
If you don't have any luck with the "contact" links, you can try the "press inquiry" links....has always worked for me with large companies. And if you don't get an email back, you can always try calling them on the phone.
