The 221B kettle, with which Sherlock boils the water when preparing tea for himself and Moriarty in “The Reichenbach Fall”. (We have a daylight video too… I’ll link to it when I find it.)
This was a 25th anniversary present from friends. It’s quite beautiful when it boils, even prettier-looking in reality than the video makes it look.
…It was in the Irish version of the Argos catalogue last year, but they removed it. I wonder if they’ve put it back since?… (For those who were inquiring: it’s a Russell Hobbs. Also: I started the video late in the boiling process. Full boil time is about 2 minutes.)
