I think this speaks for itself

Why is this hidden?

That's extra work. Fam, just drop an ice cube in it. I'm my experience it cools it down but doesn't make it taste to watery.

I actually don't get the point of this. Science side of FS, explain! Why does this cool the soup down?

Stir and blow for like 15 seconds. It will most likely cool it down more efficiently, plus save you 5 minutes on getting the straws, glass, ice, water, and assembling that. By the time you built it, the soup would be cool anyways. Work smarter, not harder.

Who eats liquid soup? Where are the vegetables?
