This is a video of Youtuber/electrical mad scientist StyroPyro constructing and experimenting with a 20,000 watt microwave oven, roughly 20x more powerful than the one above your stove. It can fully cook a frozen Hot Pocket in 10 seconds, and even melt tungsten with a 6192°F melting point. It can also create a variety of colorful plasmas. That all sounds incredibly dangerous, which is why I only built a 19,500 watt microwave. *drinks hot cocoa, melts from the inside* I should have blown on it.
