Illustration of Butterfly Balloon Modeling Course

Butterfly balloon modeling tutorial is as follows:

1. Prepare a long balloon with air in the middle and butterfly tentacles at both ends.

2. Face the middle of the balloon and divide it into two equal parts.

3. Bend and rotate along the initial distance to make two tentacles of the butterfly.

4. Rush the gas in the tentacle to the top.

5. Take out another large balloon, connect it end to end, rotate and fold it along 3/5, and then fold it.

6. Make it into the shape of X and put it together to complete the operation!

Introduction to balloons:

A balloon is a sealed bag filled with air or other gases. Balloons can be used not only as toys and decorations, but also as vehicles. 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. So it can be used to carry observation instruments and passengers.

Unmanned balloons loaded with equipment are often used for scientific research on the atmospheric environment at high altitude and sometimes for measuring cosmic rays. In most countries, cities and other places, people like to use balloons as festive supplies to decorate places on festivals to achieve the effect of rendering the atmosphere.

The origin of balloons:

In the 2nd or 3rd century BC, China invented the earliest balloon sky lantern, which was used to transmit military signals. Hot air balloon has a long history in China. It is called Sky Lantern or Kongming Lantern. Joseph Needham, a famous scholar, also pointed out that Mongols used dragon lanterns to transmit signals in the Linitz Battle of 124 1 year.
