You can cut a straight bar at will, draw two vertical lines on it, with an interval of 2 cm, and then pull it apart. See how many centimeters 2 cm becomes, and divide by 2 to know what the appropriate tensile limit is.

Slingshot practice, people keep a distance of 2 meters from the target, the target is 1 to 1.7 meters high, and an object the size of a can is placed at the target.
