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.
To find a needle in a haystack, you can use a magnet to attract the metal needle if it's made of steel. Another way is to slowly sift through the haystack carefully, separating the hay to visually identify the needle. Using a metal detector could also help locate the needle among the hay.
