Because that is just cold unburnt gas
Heating something too close to the opening chimney of a Bunsen burner can result in inefficient heating due to reduced air flow. The intense heat from the burner can also cause overheating and possible combustion of the sample or chemicals being heated. It is best to maintain an appropriate distance to ensure proper heating and prevent accidents.
Heating something too close to the top of the Bunsen burner can cause incomplete combustion as the flame might not get enough oxygen to burn efficiently. This can lead to the production of soot or carbon monoxide. It's best to position the object slightly above the top of the flame to ensure proper heating.
To put out a Bunsen burner, simply close the air vent to cut off the oxygen supply first, then turn off the gas supply using the valve on the burner. Never use water to extinguish a Bunsen burner as this can spread the flame.
Heating something too close to the opening of the chimney on a Bunsen burner can lead to incomplete combustion as there is not enough oxygen available for the process. This can cause production of toxic fumes or soot, resulting in an inefficient heating process. Placing the object further away allows for better air flow and ensures complete combustion.
Open the air hole at the base of the Bunsen burner. Turn on the gas supply and ignite the burner with a striker or a match. Adjust the air hole to control the flame size and type (safety flame or roaring flame). When finished, turn off the gas supply and close the air hole to ensure safety.
To change the flame of a Bunsen burner you must open or close the air valve, usually this is done by rotating the barrel.
because it wont work!
The movable part of a Bunsen burner is called the air hole or air vent. By adjusting the air hole, you can control the amount of oxygen mixing with the gas, which in turn affects the type of flame produced by the burner.
collar for turning to close and open the air hole air hole for allowing oxygen to mix with the gas barrel for the gas to go up gas hose for allowing gas into the Bunsen burner i hope i understood the question right?

To get a smaller flame on a Bunsen burner, slowly close the air hole at the base of the burner to decrease the amount of air mixing with the gas. This will result in a smaller, more controlled flame.
A Bunsen burner focuses a lot of heat straight upward, instead of outward. This allows you to heat something up at close range without your hand or anything else getting too hot. Most Bunsen burners have a valve that controls gas flow and adjustable vents where you can control the amount of air that feeds the flame. Bunsen burners are a safe, practical way to apply heat in a chemistry lab.
When you close the air valve of a Bunsen burner the flame turns yellow due to incomplete combustion and the ignition of carbon particles (soot).

To get a small flame on a Bunsen burner, partially close the air hole at the base of the burner to restrict the amount of oxygen reaching the flame. Adjust the gas flow to a low setting before igniting the burner to achieve a small, consistent flame.
