How to use:
1, open the package, lift the bellows cover, take out all the materials in the bellows, and then put the bellows cover tightly
2, in the windless laboratory, first put the lit incense in the ventilated place, then observed that the smoke is rising, not into the bellows.
3, the bottom of the bellows frame on the support of the iron ring above, light candles or alcohol lamp set on the bellows of the iron bottom to heat, burning incense again close to the air inlet, after a while, you will find that the smoke from the air inlet bent into the bellows, and out of the tuyere. The path of the smoke changes. How does this work?

The path of the smoke changes. How does this work?
This is because one side of the bellows outlet is heated, the temperature on this side increases, the movement of air molecules is accelerated, the density of air is reduced, and the air pressure is reduced, while the air density on the other side is relatively high, and the air pressure is also high.
In order to achieve a balance of air pressure, air flows in one direction (i.e., airflow).
The constant convection of air produces the phenomenon observed above, and thus the wind is formed.
