Why Does a Bomb Blast Create a Mushroom Cloud and Then a Ring of Smoke?

In summary, during the navy day celebrations, the marine commandos demonstrated a bomb blast by setting a time bomb in the middle of the sea. The explosion created a mushroom-shaped cloud of black gas and eventually formed a dark ring of smoke above the location. This phenomenon can be explained by the principles of vortex rings and the composition of a mushroom cloud, which can be seen in the images on the provided Wikipedia pages.

I attended the navy day celebrations and the marine commandos demonstrated a bomb blast by setting a time bomb in a small installation at the middle of the sea. The commandos dived from their boat and set the explosives from underwater.
After the explosion, what I saw first was a cloud of black gas which soon took the shape of a mushroom. Then after some time you could only see a dark ring of smoke above the location which remains for some time. How can you explain the two phenomena?
Why does it take the shape of mushroom? Why not a sphere or cube?
Why does it change into a large ring of gas which floats?

FAQ: Why Does a Bomb Blast Create a Mushroom Cloud and Then a Ring of Smoke?

What causes the ring of smoke after a bomb blast?

The ring of smoke after a bomb blast is caused by the rapid expansion of hot gases and debris from the explosion. When the bomb detonates, it releases a large amount of energy in a short period of time, creating a shockwave that pushes the surrounding air and debris outward. As the hot gases cool and mix with the cooler air, they become visible as a ring of smoke.

How does the size of the bomb affect the size of the ring of smoke?

The size of the bomb directly affects the size of the ring of smoke. A larger bomb will release more energy and create a larger shockwave, resulting in a larger ring of smoke. Similarly, a smaller bomb will produce a smaller ring of smoke.

Why does the ring of smoke sometimes have a black or dark color?

The color of the smoke ring can vary depending on the type of bomb used and the materials it contains. The black or dark color is often caused by the presence of carbon particles or other debris in the smoke. These particles can come from the explosive material or from the surrounding environment.

Is the ring of smoke harmful to humans?

The ring of smoke itself is not necessarily harmful to humans. However, the bomb blast that produces the smoke can be extremely dangerous and cause serious injury or death. It is important to stay a safe distance away from any bomb blast and follow evacuation procedures if necessary.

How long does the ring of smoke last after a bomb blast?

The ring of smoke typically lasts for a few seconds after a bomb blast. As the hot gases cool and mix with the surrounding air, the smoke dissipates and eventually disappears. However, the effects of the bomb blast can last much longer and may have long-term consequences for the surrounding area and its inhabitants.
