1. First, write the theme "Explosion Mushroom Cloud".

2. Second, use colored lead and hand-painted to design the layout.

3. Third, we should continue to add colored lead hand-painting to enrich the layout.

Finally, we will use a pencil to draw a border for adding content. This "explosion mushroom cloud" is finished.

Mushroom cloud, also known as mushroom cloud, refers to a powerful explosion cloud generated by the explosion, which is similar in shape to a mushroom, so it is named. There may be smoke, flames and sundries in the cloud. In modern times, it generally refers to the cloud formed after the explosion of nuclear weapons such as atomic bombs or hydrogen bombs. Volcanic eruption or celestial impact may also produce natural mushroom clouds.

When the fireball goes out, it forms a rising smoke cloud. The reflection of the shock wave near the projection point of the explosion center and the suction of negative pressure make the ground raise a huge dust column, and the rising dust column is connected with the smoke cloud to form a high mushroom-shaped smoke cloud.

Mushroom cloud is a large amount of low-pressure hot air that suddenly appears near the ground. Hot air rises rapidly, creating an outward downward vortex called "smoke cloud". At the same time, the vacuum state makes smoke and debris churn upward from the center, forming a "dust column" (mushroom handle). A large amount of gas finally reaches the same pressure as the surrounding air, and the rolled-up impurities are dispersed and drift downward.
