Imagine that you have one thousand bottles in front of you. You know that one of them is filled with poison and others with water, but you do not know which one is the poisoned one. The poison doesn’t look or smell different. Apart from that, you have ten bunnies with the following property: if you give a drop of the poison to a bunny, then the bunny will die at midnight. Describe, how would you find out — for sure — in which bottle the poison is, by midnight.
