Another question. :
Please, I need it urgently.
Answer:
Materials: needle, candle, wire, water cold, transparent plastic bottle, iron cone, thin wooden rod. Wind the sewing needle with the iron thread, then put it on fire until it is red hot, then immediately put it in cold water to cool it. It must be remembered that when diving, the needle must face north and south, so that it can become a small magnetic needle. Also, you have to be careful not to burn it! Cut off the neck of the plastic bottle, use an iron awl to punch a hole in the center of the bottom, then tie one end of the thin wire to the middle of the small magnetic needle, then pass the wire through the hole. Turn the plastic bottle overso that the small magnetic needle hangs in the middle of the bottle. Slowly stop the small compass needle. At this time, you will find that one end of the small compass needle is pointing south and the other end is pointing north.
