1. First draw a triangle on white paper as the rocket head, and then draw a small rectangle as an arrow to connect with the arrow body.
2. Draw a quadrangle under the arrow as the tail, and then decorate the tail with a straight line.
3. Draw the tail flame with arcs and broken lines, and finally draw a circle on the arrow body as a window.
4. Just paint the color with a watercolor pen.
Principles of rocket launching and propulsion;
The seemingly complicated rocket principle is actually very simple. As early as17th century, Newton clearly described that if a mass is thrown backward at a certain speed, it will be pushed forward by a reaction force. Hundreds of years before Newton put forward this principle, China invented and applied simple rockets, including military gunpowder arrows and festive fireworks.
