the guy Posted June 5, 2011 Share Posted June 5, 2011 about the experiment in which a 'plasma ball' or 'ball lightning' or 'plasma cloud', or whatever you wish to call it, is produced in a microwave oven by sticking a rod of carbon vertically inside the oven. (which, i would like you to know, i am not about to repeat for the sake of my microwave oven and myself) i have a few questions 1. is the 'cloud' of plasma negatively or positively charged, or neither? 2. why does it go upwards? if you stuck it to the wall of the oven sticking horizontally inwards would it still go up or would it shoot across? 3. is it hot? if so how hot? 4. also, does it have to be a rod?

swansont Posted June 5, 2011 Share Posted June 5, 2011 Probably negatively charged, i.e. electrons, and it rises because it's hot. You can use a carbon mesh. You can even do this with a grape. Google for more examples Link to comment Share on other sites More sharing options...
the guy Posted June 5, 2011 Author Share Posted June 5, 2011 (edited) ah thank you kindly also, if you used a faraday cage instead of a vase, would it also contain the ball, or would the ball pass through? Edited June 5, 2011 by the guy Link to comment Share on other sites More sharing options...
