Riddle: One day, a scientist was down in his personal lab. It was around 11 o'clock. He was working late on poisons and their antidotes. He was hungry, so he went to get a snack. Suddenly, he found himself tied to a chair. There was a nasty looking robber in front of him. The robber had his wife. He said that,' I will only leave you and your wife if you feed her 1 whole teaspoon a poison of your choice, if you don't, then I will kill you both'. The scientist fed his wife an entire teaspoon of a type of poison from his lab, but the wife did not die, how? There were blue, red, white, green, yellow, and pink colored poisons in his lab. All of them were deadly. Which one did the scientist choose?
Answer: The white one, since sugar is known as 'White Poison'.
