The Kettle That Wouldn't Switch Off

The idea: boiling water stays at 100 °C and makes steam; heat moves only where things touch.

Lan presses a new seal into the lid of an unplugged kettle while Beto holds up the old cracked one.

Every recurring character has a short tune, so you can tell who is on stage before a word is said. The tunes play only when you tap, and the Reading Access sound switch turns them off.

The Honest Page

Which parts of this story are true, stretched or made up?

True

  • Most electric kettles switch off when steam from the boiling water reaches a small bimetallic disc, which snaps as it warms. Source
  • At sea level water boils at 100 °C, and while it boils it stays at that temperature: the extra heat turns water into steam. Source
  • Heating 1.5 litres of water by 85 °C with a 3000-watt kettle takes about three minutes, if no heat is lost.

Stretched

  • A cracked seal was the whole fault. What we simplified: Kettles that will not switch off can also have a worn switch, which only a grown-up should open, unplugged, or which needs a new kettle.

Made up

  • The Mend Shed, the café and its kettle are made up. Shift and Touch come from HeatForge.

Tell it back
