Exercise:
1, first tie two red balloons into a group, then tie two yellow balloons into a group, and make these two groups of balls into a four-ball group.
2, one end of the nylon wire is fixed on the plane (such as the wall, can be fixed on the wall with thumbtacks, suction cups, nails, etc. , and then tied with a thread), the thread is straightened.
3. Put the first group of balloons, and the nylon thread passes through the balloon group and clings to the center of the balloon group. Press the index finger and middle finger of the right hand slightly along the center point of the balloon group to make the balloon close to the wall, and wind the thread around the two adjacent balloons (1 and 2 balls) on the right side of the first group of balloons for three times, and the first group of balloons will be firmly fixed on the thread.
5, pull a straight line, and then put the second group of balls, with a color (such as red) as the standard. The red ball of the second group of balls should be placed in the groove on the right side of the first group of red balls, and the right index finger and middle finger should be pressed down along the center of the balloon group to make the balloon cling to the groove of the first group of balls. First, four balls (balls 1, 2, 3, 4) adjacent to the right of the first group and the second group are wound twice, and then two balloons adjacent to the right of the second group are wound twice to fix the second group of balls.
6. Next, put the third group of balls around the four balls adjacent to the right of the third group and the second group twice, and then around the two balloons adjacent to the right of the third group of balls twice, and the third group of balls is also fixed on the line.
7, the same winding method, we put more balloon groups. The last group of balloons, two more times, cut off the lines at both ends, and completed this color training, and the colored ball chain formed a two-color spiral.
