Chinese Astronauts Demonstrate Fire in Space on Tiangong Space Station (Video)

Chinese astronauts conducted an experiment aboard the Tiangong space station, lighting a candle to demonstrate how flames burn in microgravity. The flames appeared nearly spherical, unlike the teardrop-shaped flames on Earth due to the weak combustion convection current in the microgravity environment. The live lecture, part of the "Tiangong classroom" series, showcased various microgravity phenomena and highlighted the differences in physical processes between space and Earth. The experiment would likely be met with surprise by International Space Station participants, who have strict rules regarding flammable materials and open flames.
