Sometime last year, I got really interested in microwave plasma, which can be made from a lot of things like lit matches, aluminum foil or just some grapes. However, when I went searching for more info about it, I really couldn't find much of anything. There was also no explanation as to why it was yellow every time, regardless of what it was made from. So, I decided to investigate this a little bit and try to get to the bottom of it.
