To find north you will need the magnet, a needle, a piece of very thin paper & a bucket of water. First you need to take the positive side of the magnet and slide it across the first half of the needle, as if you were striking a match, fifty times. Then do the same with the negative side of the magnet and the other side of the needle. Afterwards, put the needle in the paper so that there are 2 holes and the needle lies horizontally, then place in the water. The positive side of the needle will point North.
The idiom, finding a needle in a haystack, was first recorded in the works of Saint Thomas More in 1532. It read, to seek out one line in his books, would be to go look for a needle in a meadow.
