1. Stretch the balloon several times before inflation to reduce its elasticity.

2. Inflate the balloon quickly with a pump. After reaching the required length, the general length is about 2/3 of the length of a long balloon.

3. Before knotting the balloon, let off a small part of the gas in the inflated long balloon, reduce the air pressure, and make the balloon slightly smaller to facilitate twisting.

Specific methods and steps of balloon knotting:

(1) Inflate

Small hand pumps are mostly used for inflation (at present, there are also professional electric pumps, which are convenient and time-saving). Generally speaking, any modeling needs to leave an uninflated spherical skin at the end of the spherical skin in advance. Before making a twisted shape, it is usually necessary to determine how much air the shape needs. If the inflation is too much or too little, even if it is only a little more or less, it will affect the composition effect and production efficiency of the modeling (it takes more practice to master the inflation method quickly, so-called practice makes perfect).

(2) sealing

Common backhand knot.

Action: (Because the end of the inflatable leather is very short and the ball mouth is very tight, it is difficult to tie the knot. ) When inflating, you can move your finger away from the ball mouth or put some air after inflating to make the ball mouth part longer.

(3) Single bubble knot

It twists a cylindrical balloon into many single bubbles with different sizes according to the design proportion, and is the basic unit of balloon magic with various shapes.

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.). ) Don't exceed three or two circles at most in balloon modeling. If it is necessary to make multiple bubbles continuously to prevent the bubbles that have been screwed out from being out of line, you can hold the bubbles at the beginning of the balloon with the ring finger or little finger of the ball holder, 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) Double bubble knot

In the manufacturing process, the last two interconnected round or strip bulbs are twisted into a ring shape. 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

When making, three connected strip bulbs with the same length are stacked together, and one bulb passes through the other two bulbs 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 blisters

In production, one of the three connected bulbs 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.

Once. Annular bubble junction

Twist the cylindrical balloon into a ring.

Action: after the inflated balloon is bent and folded, hold the ball in one hand and the bubble knot in the other, and then rotate and twist.

Broken bubble knot

Blow up one of the three connected circular bubbles, so that the bubble in the modeling is disconnected from the bubble.

Action: first punch out the bubbles on both sides of three connected circular bubbles one by one? Bubble knot in ear? Every bubble should be twisted at least four or five times, and then the bubbles in the middle should be blasted with scissors or sharp tools. If five connected round bulbs are disconnected, first punch two bulbs one by one on both sides. Double bubble knot? Then pop a bubble in the middle.

Often used to separate branches and leaves of animals or flowers.

Tax. Bud knot

Self-modeling of the bar-shaped ball with a ball mouth and the head end (about 7CM) of the balloon was carried out.

Action: Hold the ball with your left hand and push the ball knot (together with your index finger) into the ball bubble with your right index finger. When the left thumb and forefinger clamp the ball knot opposite to the ball skin, with the help of the right thumb and middle finger pushing the ball skin, the right forefinger is pulled out of the ball bubble, and the bar-shaped ball bubble is rotated for 5-6 turns, and then a small amount of ball knot wrapped with the ball skin is pushed into the bar-shaped ball bubble held by the right hand with the left hand for fixation.
