How do smoke rings form?

A smoke ring is commonly formed when a puff of smoke is suddenly injected into clear air, especially through a narrow opening. The outer parts of the puff are slowed by the still air (or by edges of the opening) relative to the central part, imparting it the characteristic poloidal flow pattern.

What causes red smoke in explosion?

“You need extreme circumstances to set off an explosion. If you look at the smoke that came from the blast it’s this kind of blood red colour. That’s because of the nitrogen oxide air pollutants in it.”

What is the science behind explosions?

In order for an explosion to occur, chemicals must generate a large amount of gas within a short amount of time. When gas leaks come into contact with a source of heat, they begin to expand and can explode. If a chemical is released within a hazardous area, it can react with a heat source to cause a serious accident.

What elements make the biggest explosions?

Azidoazide azide is the most explosive chemical compound ever created. It is part of a class of chemicals known as high-nitrogen energetic materials, and it gets its “bang” from the 14 nitrogen atoms that compose it in a loosely bound state.

What does smoke circle mean?

a visible ring formed by the sudden release of smoke, usually created by blowing smoke from the mouth or by a cigarette, incense stick etc.

Why is there no smoke rings in an electric smoker?

Lump charcoal does not perform as well, producing less nitric oxide in the combustion process. Gas and electric smokers are probably the worst option if you are wanting to create a smoke ring, as they do not produce much nitric oxide as a by-product of the combustion process.

What does Black smoke mean from explosion?

Thick, dark grey smoke “pushing” out of a structure, suggests a larger, more intense fire. A fire involving petroleum products will produce large quantities of black, rolling smoke that rises in a vertical column. Smoke movement is a good indicator of the fire’s temperature.

What kind of explosion makes black smoke?

In general, a hotter fire will convert more fuel into elemental carbon, which forms into tiny particles that absorb light and appear in the sky as black smoke. A cooler combustion—or one that doesn’t work as efficiently—yields less-pure forms of carbon. These tend to reflect light, making the smoke look white.

What makes explosions different from burning?

An explosion is a violent release of energy caused by a physical or chemical reaction. It is accompanied by a rapid increase in pressure and usually temperature. The high speed of reaction distinguishes the explosive reaction from an ordinary combustion. Energy, usually heat, is needed to start all the above reactions.

How do you smoke rings in an electric smoker?

Simply sprinkle a bit of curing salt with sodium nitrite around the surface of your meat before putting it in a regular oven, and it’ll come out with a smoke ring deep enough to make it look like it took hours to cook.

What does it mean when you hear smoke from explosives?

The FBI is asking the public to tell law enforcement of any explosions they might have heard in remote areas that might indicate a “test” of the explosives. The smoke color has been an indicator of powerful explosions in some of the most iconic and devastating terrorist attacks in the United States.

What is the chemistry of an explosion?

The Chemistry of Explosions. The speed at which explosives decompose permits their classification as high or low explosives. The shock wave produced by the expanding gases causes much of the damage associated with an explosion. TNT is explosive for two reasons: TNT is composed of the elements carbon, oxygen and nitrogen.

What can the color of the smoke tell us about a bomb?

Analyzing the color of the smoke can provide information about the explosive that powered the bombs, which in turn provides clues about its sophistication — and, possibly, that of the people who made it. Such insights will be key for the inquiry, one of many pieces of evidence considered during the forensic analysis by investigators.

What causes the different colors of smoke?

Different chemical compositions, when subjected to heat and pressure, produce the different colors of smoke. “Bright white smoke, that’s black powder,” Marks tells Danger Room.
