How to fold the fingertip gyro?

The folding method of fingertip gyro is as follows:

1. First, fold the middle of the colored paper into a herringbone, and then draw the center line inward, as shown in Figure 2.

2. Turn the colored paper upside down, fold the two corners inward, and the back is the same.

3. Let's fold the two corners down again, and then fold the two corners obliquely, as shown in Figure 2.

4. We expand the corners from the middle, as shown in the figure, and then insert the corners into each other.

5. Turn the colored paper to the back and insert the folded corners according to the above steps.

6. Then just fold the colored paper in half. The following is the renderings.

Fingertip gyro is a small toy with a central symmetrical structure, which can idle on fingers. It takes a bi-directional or multi-directional symmetrical body as the main body, and a bearing is embedded in the middle of the main body to form a new type of article that can rotate in the plane. The basic principle of this article is similar to the traditional gyro, except that it needs several fingers to grasp and pull it to make it rotate.

Fingertip gyroscope has only one main physical function, that is, it relies on the principle of bearing rolling to achieve the effect of rotation. To play a fingertip gyro, you only need to provide a fixed fulcrum with the pinching force between your thumb and another finger, and then use the fingertip of the third finger to make it rotate.

In addition, the appearance design, morphological structure, main materials and surface treatment of fingertip gyroscopes are different, and appearance innovations emerge one after another, so the rotating effect of fingertip gyroscopes is diversified and plastic.
