The base and stand of the toy is ready. Take 3 ring magnets. Press fit a ring magnet on the back end of the ball pen. The other 2 magnets must attract the pen magnet. Now stick a press button in the rubber base with glue. You can see the depression in the press button.
Place two magnets on the top of the spoke. These magnets will attract the pen magnet. Place the pen tip in the button depression.
Now spin the pen. The pen will stand erect and keep spinning. The top magnets will attract the pen magnet. Here is a close-up view of the standing, spinning pen. The pen tip will spin in the button with very little friction. The wobble of the pen will stabilize itself.
You can spin this pen, write with it and again place it in the stand.
