"Yes," cried Paul and Miette together.
Then Monsieur Roger placed the glass of water in front of him, took the cork, which Miette had picked up, and forced it with his finger to the bottom of the glass; then he withdrew his finger, and the cork mounted up to the surface again.
"Did you see?" asked Monsieur Roger.
"Yes," said Miss Miette.
"You remarked something?"
"Certainly: the cork would not fall, and you were obliged to force it into the water with your finger."
"And not only," continued Monsieur Roger, "it would not fall, as you say, but it even hastened to rise again as soon as it was freed from the pressure of my finger. We were wrong, then, when we said that this same cork is a heavy body?"
"Ah, I don't know," said Miette, a little confused.
"Still, we must know. Did this cork fall just now upon the ground?"
"Yes."
