Have to share.
My daughter has a turtle tank. Turtle is named "Soup". My fault. Anyway, Soup's tank was getting ugly, so she did a full cleaning, top to bottom. Sparkling clear. But after a day or so it got a white cloud in it; looked around, likely ammonia buildup because the ammonia-metabolizing bacteria went out with the water, advice is wait a few days and it should clear up. Relayed same to daughter.
Just overheard this in the kitchen:
younger daughter: The water is cloudy though.
older daughter: Dad says leave it alone, it'll clear up in a few days.
younger daughter: Why? How?
older daughter: Dad said "Science blah blah blah..."
I am so getting a T-Shirt made. "Science blah blah blah". Highly amused.
