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. | |

I can answer almost any student science question! I especially like ones involving silkworms, spacecraft and computers. |
Hi Ashley, The problem is not so much the velocity but rather the amount of drag/friction based on the viscosity of the liquid. The more viscus, the higher the drag thus the slower it runs thru the
Hi Taylor, Since all of these liquids already are water based, I'm not sure that you will find different boiling points for them. You would be better off with liquids that are NOT water based and
Hi Holly, It may not be a direct aid to society but many of todays diseases are genetically studied and they will mark parts using the glowing gene to mark where a sequence attaches and what it does
Hello David -- It's not a daft question, but it won't work. There's not enough energy potential from skin electrodes to power anything...the voltage ranges from microvolts to millivolts, but the amount
Look it up on wikipedia. It's the way to separate a chemical (like ink) into the parts that make it up (like mixed red ink and blue ink to make purple ink). http://en.wikipedia.org/wiki/Chromatography
