Clever, isn't it?
as our kettle broke this weekend?
We're boiling water on the hob like the olden days.
What happens is that when the water boils, some of the steam is channelled through a part of the kettle where the switch is placed. There is no water there, as this channel in the kettle leads out to the outside air.
Hence the switch can be set to operate at a wide range of temperatures (say anywhere between 80degrees and 100degrees), because only when the kettle actually boils does the steam get produced and travel along the cavity in the kettle that contains the switch.
So the switch only "knows" that there's hot steam flowing around it, it does not "know" what the temperature of the water in the kettle is.
This makes for a cheaper (less sensitive and accurate) switch, and it ensures the kettle only switches off when it is really boiling, not just hot.
as I have a penis.
It's called theWZA!!!!!!!!!
I thought you were a lady.
(I should probably confess that I didn't write the above anyway)
He waves a flag when he thinks it's boiling and 3 other little men with a pulley pull a switch to switch it off.
it's because the little men have died.
apart from small things that have a very very slow metabolism
they need to invent that.
*queue a load of people saying that already has been invented.
Its a timing thing.
It's just luck.
It upsets me.
Our £6 Morissons toaster is bonza, though.
i then can fill my kitchen with steam. it's fun.
And it just boiling away until I close the lid.
I had to put something heavy on the switchy thing. Sometimes I forgot to take it off.
and it was invented by this dude:
Who is obviously loaded now.
and then when the scout leader finishes touching you the water would be about done
I love that thing.
it's in a perpetual nightmare
the man who makes all the kettles.
he has a kettle for a head, right?
