Now run your straw through a concentric larger straw and pump -30C glycol through the annulus. You can get your 96C tea down to 54C in seconds! Think of the efficiencies gained!!
Can I add RGB?
You'd be irresponsible not to
Of course! That increases efficiency by 69%!
Nice.
No! Not my annulus!
it's more likely than you think
Proctologists hate this one simple annulus trick
mmm... annulus
But the goal here isn't to maximize cooling, you still want the tea to be hot, just drinkably hot rather than dangerously.
You need to calibrate your coolant water temperature to provide the ideal amount of cooling for you.
- Use a metal straw to improve heat conduction.
While metal is a better conductor of heat, when looking at the effective rate of cooling you need to take the wall thickness into account. I think a plastic straw with it's micrometer thin walls is unbeatable.
Edit: I have trouble finding information on wall thickness of drinking straws, it one source says they are 130-250 μm thick. That is thicker than I expected.
Counterpoint: drink a cold drink through a plastic straw and a metal straw, with your fingers on the straw. See which one feels cooler.
Leave a block of wood and a brick of steel in a freezer for 24 hours and see which one feels cooler - they’ll be the same actual temperature (at least negligibly close the longer they’re left) but the metal will feel immensely cooler to the touch due to its higher capacity for heat transference.
This man HVACs
Very low surface area heat exchanger you've got there! Gotta do several more loops under the water to get efficient heat transfer.
Well that's why they invented crazy straws after all!
I love plastic straw in hot tea!
Y'all trying to come up with ways to cool it while I'm using my 5 temperature setting electric kettle to get the water hot enough to steep tea, but not boil.
But can you play snake on your kettle
I bought a kettle with a temperature selector. I have one degree of precision. Which is often overkill. It's surprisingly useful to be able to heat water at non scalding temps. Especially for cleaning tasks, actually.
Motherfucker never heard of ice cubes
Ice cubes can water down your drink. Use a large, frozen, steel ball bearing so you can instead get some nice heavy metal poisoning to accompany it.
(Don't actually do this)
You should use lead instead of steel. The higher density makes the effect longer lasting.
It also makes it sweeter!
There are alloys of stainless steel (I forget the numbers off the top of my head, it’s been more than a few years since I worked in that field) that are perfectly fine and compatible for food/grade hot-process work.
I have these things called cold rocks for my scotch - they’re some kind of stone or earthenware dice-sized cubes that you leave in the freezer. Bought them at an alcohol warehouse shop we have here in Australia called Dan Murphys. They’re great for cooling without diluting.
Just get one of those handy cupholders that come free with lots of electronics:
They also work for quick thawing.
Hmmm microplastics soup
Wouldn’t the plastic straw melt in the hot tea? Maybe need metal or silicone straw adapter hooked onto plastic straw in heat exchanger 🤔
Don't think most plastic straws would melt, but they would probably soften and might infuse more chemicals into your beverage than it would if it were cold. At this point I'd just go for the obvious solution of repurposing an old heat exchanger from an AC unit or something. The strange taste will go away after a few times (probably).
Personally I would use my knowledge in aerodynamics by blowing on the tea before sipping
Tasty coolant flavoured tea
Yeah, I won't drink anything hot out of plastic anymore: Corpos lied to us for decades that it was safe but it wasn't and now we're full of all sorts of terrible shit. The straw probably wouldn't deform, but it probably would leech all sorts of chemicals into the water.
It's plastic not wax
Oh dear this had me I stitches. Can't explain it. It tickled me just right.
Paper cups are wax coated, so it also depends on the wax as well.
MacGyver at Wish
MacGyver gets bored when he doesn't have something important to do.
It would cool it down, but how much would be the question.
Fridges cool your water in them using the same principal, a loop of tubing is in the fridge which cools the water as it passes through.
It would entirely depend on how fast you suck.
Even moderately cool water would work if you just drank slow enough, and ice water wouldn't work if you drank too fast.
I'm sure some engineer could do the math on how cold the water would have to be to cool boiling water at maximum vacuum.
I suck pretty hard.
Just mix them together.
but am patient
Post memes here.
A meme is an idea, behavior, or style that spreads by means of imitation from person to person within a culture and often carries symbolic meaning representing a particular phenomenon or theme.
An Internet meme or meme, is a cultural item that is spread via the Internet, often through social media platforms. The name is by the concept of memes proposed by Richard Dawkins in 1972. Internet memes can take various forms, such as images, videos, GIFs, and various other viral sensations.
