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 What kind of cloth holds stains the best any good stain websites?
Answer Hello -- you'll find lots of information on stains searching the internet, because almost every stain remover manufacturer has a website with stain removal instructions. You can also write down websites when looking in the stain remover aisle in the supermarket, each product should have a web address printed on it.
In general, natural fibers (cotton, wool, silk) hold stains the best (or worst, depending on if YOU are doing the laundry or someone else!). Their fibers are hollow, and stains that get inside the hollow fiber tubes are very difficult to remove. Stains that stay on the outside of the fibers are much easier to remove. Synthetic fabrics are not neccessarily hollow, and 'stain resistant' cloth is coated with a film of plastic or other chemical to prevent the stain from getting inside the fiber.
