1. Stretch the balloon several times before inflation to reduce its elasticity.
2. Inflate the balloon quickly to the required length, which is generally 2/3 of the length of a long balloon.
3. Before knotting, release a small amount of gas in the long balloon to reduce the air pressure, so that the balloon is slightly soft and easy to shape.
Whether using one or more cylindrical colored balls to make complex or simple shapes or decorations, big or small, you need to master some basic manufacturing techniques and crafts, such as inflation, sealing, single bubble knot, double bubble knot, triple bubble knot, ear bubble knot and so on.
1. Small hand pump is mainly used for inflation. Generally speaking, any modeling needs to leave an uninflated spherical skin at the end of the spherical skin in advance. Before making a model, it is always necessary to roughly determine how much air the model needs. If it is inflated too much or too little, even a little more or less, it will affect the composition effect and production efficiency of the model.
2. Common backhand knots are often used for ligating the ball. Action: (Because the end of the inflated ball skin is short and the ball mouth is tight, it is not easy to ligate) When inflating, you can move your finger away from the ball mouth or deflate a little after inflating to make the ball mouth part bigger. In addition, the ball will soften slightly after releasing a little gas, which also avoids the tension of twisting and other actions and the occurrence of ball explosion in the future.
3. Single-bubble knot system is a basic unit composed of colored balls of various shapes, which twists cylindrical colored balls into many single bubbles of different sizes according to the design proportion. Action: Hold the ball in the left hand and knead the cylindrical ball into a bubble shape in the right hand. At the same time, both hands rotate the ball in the opposite direction to make it twist. In most cases, the twisting action of any bubble (including double bubble knot, triple bubble knot, ring bubble knot, etc.). ) Not more than three or two times in the color ball modeling. If you need to make multiple bubbles continuously to prevent the bubbles that have been screwed out from being out of line, you can use the ring finger or little finger of the ball holder to hold the bubbles at the beginning of the colored ball, and at the same time free your thumb and forefinger to cooperate with the other hand to continue screwing. In addition, if the torsion and rotation directions between parts are consistent, it will be more conducive to rapid manufacturing and convenient adjustment and disassembly.
4. In the production of double bubble knots, the last two round or strip balls are connected by three and twisted into a ring. Action: While bending the last two bubbles with both hands, put the thumb and forefinger of the left hand holding the ball at the bottom of the bubbles and gather them together, and then rotate the two bubbles with the right hand to twist. It is often used to make limbs of animals or branches and leaves of flowers.
5. Three-bubble knot In the production, three connected strip bubbles with the same length are stacked together, and one of them passes through the other two bubbles and is wound into a whole. Action: Gather three strip bulbs with both hands, separate the strip bulbs on both sides with the left and right palms and thumbs, and push the middle strip bulb through with the index finger and middle finger of both hands. Often used to make animal carcasses or tricolor chain ornaments.
6. Ear ball knot In the production, the ball in the middle of three connected balls is screwed by itself. Action: While bending the three bubbles into a ring with both hands, put the thumb and forefinger of the left hand holding the ball at the bottom of the bubble knot of the two bubbles and gather them together, and then gently pull up the bubble in the middle with the thumb and forefinger of the right hand and twist it by itself. It is often used to make animals' feet, ears and leaves of flowers.
7. Ring bubble knot Twist the cylindrical colored ball into a ring. Action: After bending and gathering the inflated colored balls, hold the ball in one hand, pinch the bubble knot in the other, and then rotate and twist. It is often used to make heads, limbs and leaves of animals and flowers.
8. Bubble-breaking knot explodes a bubble in the middle of three connected circular bubbles, so that the bubble in modeling is disconnected from the bubble. Action: First, tie an "ear bubble knot" on both sides of three connected circular bubbles one by one. Each bubble should be twisted at least four or five times, and then use scissors or sharp tools to explode the bubble in the middle. If five connected circular bubbles are disconnected, first make a "double bubble knot" for the two bubbles on both sides, and then blow up the bubble in the middle. Often used to separate branches and leaves of animals or flowers.
9. The strip-shaped bulb at the tip end (about 7CM) of the bud-knotted colored ball is shaped by itself. Action: Hold the ball with your left hand and push the nipple (together with your index finger) into the bulb with your right index finger. When your left thumb and forefinger hold the ball nipple through the ball skin, with the help of the right thumb and middle finger pushing the ball skin, you will pull the right forefinger out of the ball bubble and rotate the bar-shaped ball bubble for 5-6 turns. Then, with the left hand, push a small amount of ball nipple wrapped with ball skin into the rod-shaped ball bubble held by the right hand and fix it.
