Pull one, two, or three billiard balls and see different effects, endless fun
There are many ways to play, it all depends on your imagination. The ball cannot move forever, it will only move forever in a specific vacuum state. Those who are uncomfortable with this should avoid it!!!
Use a ball to push the other four balls, and you will find that only one ball will swing back and forth; if there are two balls, both balls will naturally swing.
Without the need for electricity, the ball can be made to swing evenly, which is a small craft item for passing time when bored.

When you don't want to fall asleep and you feel pain? When you count sheep one by one, do you feel that you are too naive?
Then please use this, rest it on the table, and move your eyes as the iron ball collides, and in no time at all, I guarantee you'll fall asleep peacefully!
