You can make plasmas in your microwave oven by putting a carbon mesh (called carbon veil) strip on top of a ceramic cup turned upside down and running the microwave on, creating balls of plasma about the size of a fist that are orange-white, float around, and hum at the 60 Hertz frequency of the magnetron, eventually hitting the ceiling and peeling all the paint off the top.

“you can make plasmids in your microwave oven have you ever tried that you mean putting a metal fork and your microwave and turning it on well not a medal for it that'll double spark but that's not what you want you take like a ceramic cup and turn it upside down and then find some thin carbon mesh they call it carbon veil and put a little strip in there on top of the thing”
