i did something similar at work once
in one of our tea cabins (building site; we work in cabins. no i'm not a logger, much as i'd love to be).

nobody was in but me one day, and on this day i just happened to discover by accident that if you leave the lid of a kettle open, it affects the thermostat in the kettle so as it never clicks off, and will continue to boil endlessly (not sure if this is true of all kettles, or just of the £4.99 one we got from argos). anyway, que me closing all the windows, shutters and doors and boiling a full kettle of water non stop for about 20 minutes until the room was filled with steam and i literally couldn't see my hand held up in front of my face.

that was fun. not entirely sure why i did it though. i was also terrified someone would call the fire brigade when i finally opened the door and lots and lots of steam came pouring out that could easily have been confused for being smoke from a cabin on fire. luckily our site was based on a council estate in ealing though so nobody gave a fuck.
