1, inflate a long balloon to make it expand, then tie a knot at the tail of the balloon (the balloon should not be inflated too slowly, and it will easily explode when twisted), leave three quarters of the position at the tail, screw the first balloon and the balloon at the tail together, and then determine how many small balloons to twist according to what you have made. After making the same balloon, screw each balloon together and put it together.
2. You can put many shapes of balloons in a round balloon, and the shape is whatever you like. Blow up the small balloon inside and inflate the big balloon outside. The nodding tail is a beautiful balloon. You can also put petals, pieces of paper, colored paper and so on in the balloon.
