In many places in America they put sugar in coffee

Now I have a sticky cup

To indulge in some pedantry, the cofee isn't hot enough to melt sugar. Instead the water vapor condenses and collects on the sugar, dissolving it.

Ok, I like coffee, and I like cotton candy, and this is cute, so I almost hate to criticize it.

But isn't the cup just going to get all sticky? The bigger the cup, the quicker it will cool, and the more coffee you'll need to fill it. You'll only get a few "raindrops" of sugar before the steam stops coming off the cup. That's barely any sugar, especially for a large cup. What do you do with the rest of the cloud? Are you supposed to smoosh the rest into your cup? Because that seems like too much sugar. Or do you share the cloud with people at your table?

I think this concept would be better actualized as part of a dessert. Maybe like a hot peach cobbler or a sticky toffee pudding. Something that stays steaming for a minute, and you want to wait for it to cool, and it won't need sugar but the little drops of sweetness won't make it too sweet.

Hmm sugar on the handle.

…is Singapore not real life?

Very cute, but sugar in my coffee?!? Eew!
