The concept of anti-spin is not prop specific. This concept explains an object’s rotation in relationship to your manipulating body part, usually the hand or the arm.

When an object is moving in a circle, “anti-spin” is used to describe the object rotating in a direction opposite its movement. In simple terms, the object is moving clockwise and is in anti-spin if it is simultaneously rotating counter-clockwise. In order to understand anti-spin, we need to understand its opposite, in-spin. An object can move in a large circle (hand path) without any rotation. When you force the object to rotate, it forms smaller circles around the larger circle. When the smaller circles are moving the same direction as the larger circle, this is called in-spin. If we stop the spinning of the small circles, but maintain the same direction for the handpath, and spin the object the opposite way, that’s anti-spin. The counter-rotation or retrograde motion of the spinning object. We can switch from anti-spin to in-spin by changing the rotation of the prop. We can also do this by keeping the rotation of the prop the same and changing the arm direction.

Knowing the difference between in-spin and anti-spin is a mental process. You will have to think about how they feel different. Once you become familiar with this, you will know whether or not you are in-spinning or anti-spinning.
