You see, condensation is formed when moist air is cooled below its dew point.
The wings produce lift in part by causing the air under it to move slower than the air above it, leading to lower pressure above the wing. Since pressure and temperature are directly related, the temperature drops and we see clouds forming.
(Obv joke, just in case)









Oh, reduced the time by 8 minutes.
I was wondering what sort of kettle you were using that was almost as slow as a stove. Mine takes under two minutes for 2 cups (0.5L), so it checks out.
Happy brewing!
