Explain what the guillotine is, why people thought it was an effective means of punishment, and what happened to the remaining "pieces".
Guillotine is when the prisoner's head would be chopped off by a sharp blade. People thought it was a more efficient and quicker way to end one's life, as opposed to hanging. It didn't really work, because the nerve endings would still fire for a few minutes, causing the face to twitch.
