A metal detector.
Use a metal detector and hope for the best, or burn the haystack.ImprovedMeaning: extremely difficult; extremely rareExample:Trying to find your class room in the engineering building is like trying to find a needle in a haystack.I can only think of three options:1. Using a magnet to attract the needle,2. Burning the haystack so only the needle will be left behind, and3. Put the whole lot in a basin of water. The haystack will float while the needle will sink to the bottom of the container.
