Sophist: Hey, I wonder what would happen if I put powdered milk into carbonated milk.
*5 minutes later*
Sophist: My cereal is loud and it's demanding to know why I would sin against both nature and God so thoughtlessly.
Nick: How does it taste...?
Sophist: Bad.
Brent: The fizz comes from the carbonic acid in the water splitting up into CO² and H²O over time. And carbonic acid is - as an acid - sour. By adding milk to sour water, you've created a very convincing emulation of spoiled milk, so I'd believe in an instant that the taste is not great.
Sophist: I have mastered the potion: Instant Spoiled Milk, therefore earning the rank of Shittiest Alchemist Currently Alive.
