If I read your question correctly my answer would be heat convection. The air around the Bunsen burner is being heated thus it will rise and cause a vertical "wind".

∙ 12y agoBecause of the convection currents caused by the heat - heat rises and this causes it to spin :) xxx

What are the different methods and techniques in heating liquids?
The most common method is a test tube held with a vice clamp, over a Bunsen burner usually with a blue flame hope this helps =] x
What are the temperatures of the Bunsen burner flame zones?
A Bunsen burner flame consists of an inner cone and an inner cone. In the inner cone, no combustion is occurring and the inner cone consists of a mix of air (which has been introduced through the vents in the bottom of the barrel) and gas. In the outer cone, combustion is occurring. Hence a Bunsen burner flame is "hollow;" there is no flame in the inner cone. Because air, containing oxygen, is present in the inner cone, it is called the "oxidizing zone." A piece of red hot copper held inside the inner cone will oxidize, being covered with a layer of black copper oxide.
Where should a beaker be placed with respect to the flame for the most efficient heating on Bunsen burner?
The most efficient, and safe, place for a beaker to be heated is above the flame. Have the beaker held up by the proper metal stand and have it held so that the flame is grazing the bottom of the beaker. Be careful though, the flame should only graze the bottom of the beaker so that the chemical doesn't heat up too quickly.
What is fire polished glasses?
Fire-polishing is a technique used in cleaning test tubes in labs and getting the lip of the test tube slightly annealed ( heat treated ) making a circular ( like cleaning drinking glasses) motion held ( in a secure holding device) in the flame of a Bunsen burner, best done with Pyrex or other heat-resistant tubes. I have seen it done. Mrs. Lamour used to practice this technique in Stevens Academy. it is a cleaning practice.

When a substance is placed over a Bunsen burner it?
typically undergoes heating and may undergo a phase change or chemical reaction depending on its properties. The Bunsen burner provides a consistent and controlled source of heat to increase the temperature of the substance, allowing for various processes such as evaporation, combustion, or decomposition to occur.
Why should the matchstick be held 1 cm below the nozzle when lighting the Bunsen burner?
WHO is teaching you to light Bunsen burners with matchsticks? That is so unsafe and wrong. You can get burned really easily like that, and Bunsen burner burns are always bad. Go to a hardware store and spend $5 on a spark lighter, like welders use to light their torches. Those are a safe way to light your burner.
Why does the blue flame on a Bunsen burner make metal things red when they are held in the flame for a long time?
I t happens as the heat makes the metal glow as it expands.

What is the function of testube and a testube holder?
The testube holds liquids and other scientific substances. It can be held between two metal prongs known as a testube holder. Often, a testube holder raises the testube over a bunsen burner (an open flame).
