Things You'll Need
Instructions
Place a pencil into the hole of a thread spool so that the pencil will stand up stable without being held with your hand.
Hold one side of a ring magnet against the north side of the bar magnet. Watch for whether the magnets stick together or push away as the latter means that the ring side is also north. Place the ring magnet, north side up, over the pencil so that it falls down to the top of the thread spool.
Test the other ring magnet on the bar magnet's north end, watching for the magnet to attract or repeal. Place the ring magnet over the pencil, north side facing down, so that it falls towards the first magnet. Watch for the first ring to repel the second ring, causing it to levitate.
