Necessary materials: paper, pen and pigment.

1. First draw three groups of straight lines with different lengths, as shown in the figure below, and determine the position of the main part of the rocket.

2. Then, connect the lines and draw the rocket head, tail and booster on both sides.

3. Draw the flame shape at the tail and the gas shape around the rocket when it is launched in a simple arc.

4. Next, start to color the rocket. First, paint a red rectangle on the head of the rocket to represent the national flag, paint a red square on the lower part of the main cabin of the rocket to represent the number position of the rocket, and paint red and yellow flames on the tail of the rocket.

5. Finally, write your favorite number in the serial number position of the rocket, decorate the rocket with some sky-blue lines, and paint the gas around the rocket with gray and yellow edges, and that's it!
