So... about Penguin Movement Efficiency?
"So..." King Leroy said. "We were supposed to be talking about making penguin locomotion more efficient?"
Sir Penguin Newton put away his glass prisms and the rainbows disappears. "Yes, yes, of course," he said. "Let me show you my latest invention."
"Is that a penguin launcher?" King Leroy asked.
"What is wondrous about this device is its symmetry. You exert a force on the elastic band in one direction and the elastic band exerts a force of equal magnitude in the opposite direction! Then, when you release the elastic band, a sudden unbalanced force leads to an acceleration that sends a penguin flying forever and ever."
"Forever and ever??" King Leroy asked. "Are you sure about that?"
"Well," Sir Penguin Newton said, "it would if the penguin were in the empty vacuum of space."
"Now, why do objects move ceaselessly in outer space?""
