I was wrong about kettles

[irakyl]

Ah, so THIS explains why my kettle kept turning off when I blowed through the metal tube!!! I thought it was just a breathalyzer to make sure you were sober when boiling any liquids.

Steve Mould is a blessing for infotainment (and humanity in general)

But this also produces a problem, if the lid isn’t closed, then the kettle will boil dry

I think a temperature sensor would work as well if it would check the temperature change with a differentiator circuit. If the temperature does not increase while heat is supplied, the water must be boiling.

Keep up the good work steve, I'm sure the shorts channel will grow just as big, if not bigger, than your main channel.

But I have a kettle that switches off at 60, 70, 80, 90 and 100 degrees. Exactly. Any explanation would be welcome. It does have a digital display on it so..?

[lenkagamine]

Oh i thought this would be a follow up, like something new or a correction to the last video

[seanbrockest]

This is what I like about real learners and real teachers. You made a video confounding yourself as you tried to figure out why kettles weren't behaving the way you'd hypothesized they would. In the end the only conclusion left was that you were wrong. Your entire hypothesis and understanding of the mechanism was wrong. Not only were you okay with that, you SHARED it with us. You took us along, you let us witness you squash your bias, and you followed up with the correct answer. Most people would have hid their journey because it showed a former state of ignorance, but you didn't. This deserves applause.

Interesting. Not sure mine has a tube like that

[RobotProctor]

I literally watched this video yesterday and still clicked on this...

CHALLENGE FOR STEVE MOLD. . So if the metallic disc was already at a higher temp than the vapor would be. would the kettle shut off or would it just not run to start with?? Example. A liquid that’s boiling point is only 10-15 degree above room temp?? I guess you would have to know what the temp threshold of the strip is and choose a liquid that boils lower than the buckle temp of the metal strip. Then it should definitely boils dry. Challenge. Boil a liquid away without tripping the switch

[SandTiger]

Yeah. But my lid broke off and mine still shuts off. Albeit it a bit later after boiling. Backup is probably on heating element.

[jasonbouvette]

Try an American drip coffee maker. There is a hot plate that keeps the coffee warm, without some funny tube....

[dazperson]

Does this mean that if you were to "boil" something like liquid nitrogen it would still shut off? Or does the disc rely on warmer gas to deform?

[rivers]

It's a fair enough assumption because that's exactly how rice cookers work (with the thermal switch)

[brando_handle]

Why in the world would this clip be a summary of the last vid

[tjsudac]

I have a kettle you can choose 60, 70, 80, 90, 95 or 100 degrees of C. How does mine work?

[NGC-]

Incorrect, there’s actually a tiny kettle fairy inside each kettle that flips a little leaver to turn it off when they hear it boiling.

[DaviddeKloet]

Didn't you just post a video about this a day ago? The title suggests there was something wrong with that video but it seems to be saying the same as that video.

[deos]

Me when I watch the video: *chants BIMETALLIC STRIP* watches more *FUCK*
