I. Tools/raw materials

Two 260-long balloons, one green as a pedicel and the other color as petals (yellow in the demonstration).

Two. Methods/steps

1, the yellow balloon expands to the remaining end about 3 cm long.

2. Fold the balloon in half, and tie the air nozzle with the remaining end of step 1 to make the balloon a ring connected end to end.

3. Adjust the knot to the center of the balloon.

4, twisted into two circles, a bit like a bow. What we just twisted is called "fulcrum"

5. Press the midpoint of the balloon ring on one side of the fulcrum to the fulcrum, and then screw the midpoint and the fulcrum together.

6. According to the method in the fifth step, press the midpoint of the big circle toward the axis, and then screw them together to form four rings.

8. Those are four rings. Tidy them up and make them look like petals.

Third, balloon introduction

A balloon is a sealed bag filled with air or other gases. Balloons can be used not only as toys, but also as vehicles. There are many kinds of balloons. Now we mainly introduce balloons made of natural latex, which can be used as decorations and arches for the opening ceremony, printed with their own advertising patterns as publicity, and printed with photos of married couples as congratulations.

As a toy, balloon was once called "foreign eggplant". There is a small bamboo whistle at the opening of the balloon. When the balloon is filled with air, the exit will make a loud noise when it opens. Balloons can also be used as decorations and transportation. If the balloon is big enough, the gas in it is lighter than the air in the same volume, and the buoyancy generated exceeds the weight of the airbag and attached objects, the balloon can rise.
