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
you trying to make the tea fly?
I think they’re trying to use their knowledge of convective heat transfer vs conductive heat transfer.
No no, he's making sure to provide downforce not lift.
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.
It has “that breast implant is an animal” vibes.

Paper cups are wax coated, so it also depends on the wax as well.
It turns out plastic can melt. Crazy, I know
The melting point of plastic is 300+ degrees Fahrenheit. Even if you tried to drink tea that was still boiling in the cup you’d damage your mouth pretty good but the plastic straw wouldn’t melt.
This isn't exactly true. Plastic is all different types of things and there is no one melting point, for example PLA (poly lactic acid) which is commonly used for things like disposable drink lids has a glass transition temperature of 60c (140f). Abs (acrylonitrile butadiene styrene) has a glass transition temperature of 105c (221f).
While the full melting point for these two polymers is higher than the glass transition, at those temps, your straw will start turning into a nice wet noodle.
The melting point isn't helpful here because it defines the point at which the object turns into liquid, not the point where it deforms or gets damaged.
A drinking straw like that is likely made out of polypropylene with a melting point of 320F. Though the comment I replied to said “melt” specifically, if you wanted to reference the point before it begins to soften, PP has an operating temperature of almost 200F still. So that includes any hot liquid up to the point of near-boiling, which will be a bigger deal to your mouth than the straw. Thats why it’s used in drinking straws and the like.
Just go full metal. Better heat transfer.
