Does It Dissolve or Float?

My hubby keeps me laughing. I think the quality I have always liked most about him is his sense of humor.
Last night he had insomnia. This morning I asked him what time he got to sleep and he said it was after 3:30. About 3:15 he got up and came down to the kitchen for some milk. He said, "I found out one thing. Nutmeg does not dissolve. It just floats on top of the milk no matter how much you stir."
And that reminded me of the time we came home one evening and found pepper and sawdust (I think it was) floating in water in the bathroom sink . Puzzled, we asked the girls who had done it, and found out it was Robin. "I wanted to see if pepper and sawdust would float."
As they say, the acorn doesn't fall far from the tree.
