Plasma and magnetic fields

  • #1
For a science fair experiment me and my partner created plasma using a microwave. We used two different methods which both had different results. For the first one we simply put a match on a raised surface and put a beaker over the top using small pieces of cork to elevate the blacker so that oxygen could reach the match. We then lit the match and turned the microwave on. It created a beam plasma that went to the top of the glass beaker, and lasted for about 20 seconds. Then we did a second plasma using grapes. We simply cut a grape in two, leaving just the skin, and then placed it into the microwave. It created small bursts of plasma for about 8 seconds. Why did they have different results and how did it work?
Thanks in advance
