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.
