How to Put a String on a Yoyo and Adjust it for Play | …

Now if you have a responsive yoyo, with a bearing or wood axle, using a double loop or a triple loop will cause the yoyo to play a little bit differently. If you have a fixed axle yoyo it will keep the yoyo from sleeping so if you have a little brother or little sister and you want your yoyo to play easier for them, you can always double loop it and that will make it easier until they get a

Ball bearing - Wikipedia

A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most
