00:30The heat generated by combustion, cooling down, and cooling down
00:36forms an ineffective current.
00:38Therefore, the flame of the candle will follow.
00:43In the space station, the microgravity environment
00:46almost eliminates this kind of ineffective current.
00:50After combustion, the gas moves in the same direction.
00:56Therefore, regardless of the direction of the candle
00:59and the direction of the flame,
01:01the flame will form.
01:05This is a low-temperature performance.
