yes there is , in chemistry they have this weighted object that is put in solution to stir it while its hot.
Bro has never seen boiling water.
I could swear I've seen some sort of small three pronged thing that you drop into your pot, and as the liquid boils, it spins and stirs it.
Convection currents have entered the chat
It's called soup.
Then my soup isn't working.
Well I didn't want to say anything, but now that you brought it up...
True, there are soups like that.
It shouldn't be difficult at all to add a stirrer that gets spun by the inductive field of an induction stove.
What I'd love to have tough is a pan with built-in temperature sensor, so that I can control the temperature of the pan directly instead of only being able to control the energy output of the stove.
You've got a bright future in crazy Victorian inventions if you can make a steam-powered time machine to get there.
That only makes me think of the inevitable outcome:
Bright past.

At a rolling boil you could probably get the pot stirring itself with surface geometry. Bubbles boil upwards, so putting the right fin shape should get it spinning. Seems like it would require a bunch of machine work so it would probably be prohibitively expensive to make.
This exists. I tried to find a link or video but it seems to have disappeared.
Edit: Here's a page on it. It's from 2012 though, I guess the idea never really took off.

I had a friend with a similar pot (might have been the same one shown there) and... oh my god, it was impossible to wash. Just awful. Neat to watch but oh man, never got used after that.
Is it this one? https://www.youtube.com/watch?v=91yoFz5XFqY
Looks like it!
Can you imagine cleaning such a monstrosity though?
This already works with noodles if you place them vertical the middle and then twist them and let them fall in a spiral pattern leaning against the edge of the pot. As they soften and fall in they will spin in a toroidal shape powered by the bubbles.
With modern induction cooking this should not be as problematic. You can use the magnetic field to put something in motion
If you get a good rolling boil, you shouldn't need to stir macaroni.
Tho it is a bit of a waste of energy, since a rolling boil is more than you need to cook pasta.
I remember my high school science teacher saying that once you reach boiling point any extra energy input is wasted.
That doesn't seem to be true in practice though.
I guess in a full rolling boil more of the water is at boiling point rather than just the layer at the bottom.
I think there is some chemistry equipment that does that?
hot plates have a motor and a magnet that couples with a stir bar.
there is however this sort of thing for stoves: https://www.amazon.com/JossaColar-Fireplace-Electric-Accessories-Thermometer/dp/B0BDM14HVM
That's for a wood stove, to distribute heat throughout the home. While it might be possible to repurpose it, I don't think it's very practical
Stir plates use magnets and magnetic stir bars, and can be used without heat
Made my own stir plate once with a computer fan, magnets, and a potentiometer. I am sure they come with heat if needed. They can come with extremely large stirring bars.
Ok here’s my pitch: a pot with a steam powered magnetic stir bar system built into a sealed loop in the bottom.
I've thought long about this, specifically those devices that use the pizeo electric effect to move a fan.
Problem is that you need a temperature difference to make the effect go. But ideally I'm imagining a fish that swims around the pot converting heat to work.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
