How to make a globe with table tennis?

First draw a circle in the middle of table tennis with a red pen as the equator; Drill a small hole on each side of the equator so that the distance from the small hole to each point of the equator is equal.

Then bend the wire into a semicircle. Note that the diagonal wire should make an angle of 23 or 5 with the vertical, and the bending angle is slightly larger than that of table tennis.

Then put the ping-pong ball on with a diagonal thread.

At the two ends of the diagonal wire, tape is wound several times, so that the table tennis can be fixed in the middle of the diagonal wire and can rotate freely at the same time.
