Earlier quoted context omitted.
In the late 90s, someone in my house decided to put an orange in a microwave for 30+ minutes just for the hell of it. Nothing happened for the first 20 minutes or so, but then the orange cracked open and belched out thick black smoke that smelled _disgusting_. At some point I'm going to sacrifice an old microwave and recreate this experiment outside; I'm desperate to know what the heck is going on with that microwave…
Another fun experiment is to slice a grape in half and stick it under a glass cup, then start the microwave and step the hell back. Also, never ever put an egg in a microwave. I accidentally made that mistake and it blew the door open and shattered the glass dish. Might as well have microwaved dynamite.
