00:30The heat generated by combustion, cooling, and cooling

00:35form an inefficient current.

00:37As a result, the flame of the candle will not be able to catch fire.

00:42In the space station, the microgravity environment

00:46almost eliminates this kind of inefficient current.

00:49The gas after combustion

00:51moves in the same direction in all directions.

00:55Therefore, no matter which direction the candle is facing,

01:00the flame of the candle will not be able to catch fire.

01:04This is a low-temperature performance.
