This is from a meta level positive rant I temporarily appended to an answer to a question about performing the Cavendish experiment at home. I realized how few lab type experiments we reference here, and how useful they would be for students.
"Editorial (I'll move this positive rant to meta soon) - given the obviously widely varied audience on this site, I would very much like to see more questions like this one relating to amateur or home experiments. The analysis of the data and possible sources of errors in these experiments is often subtle, and is very instructive. To have real physicists and other clever students publicly criticize some aspect of an experiment that is actually being done at home or in a school lab provides something that many students may never get otherwise. The social network framework will help many newcomers from different countries learn what real science is in a way that yet another dose of imperfectly understood theory never will. And it's fun too."
You see my point? Maybe we can make a "doable experiment" tag, and have sort of lab teams or something in chat rooms, making suggestions or something. Any ideas?
