That's kind of disgusting. So southern style sweet tea is basically just tea flavored simple syrup?

Masshole that lives in the south I have no idea how everyone I know isn't on insulin. Sweet tea is an abomination of sugar.

Where did you get that? It would be like honey if that was correct. Also, that is not called suspension but solution, since the particles dissolve (unlike fat in milk, but that is an emulsion since the fat is a liquid).

I thought a supersaturated solution could easily be brought out of supersaturation by something like sticking a spoon in it? Am I misremembering?

I highly doubt that, since any shock or impurity would cause a supersaturated solution to separate into a solution and the excess sugar.
