A good slingshot must be in the shape of a Y, and made from a sturdy wood. The most important is that the two leather cords must be of equal length. If not, the slingshot would not be accurate.
Derived from the slingshot, the scientific principle of this episode discusses that the rotation generated when an object travels may cause irregular shaped stones to experience uneven air resistance, causing the object to stray and not hit the target. The shape of the object effects its movement, and can greatly affect the shot accuracy.
