12. Astronauts And the Fire Experiments in Space
Astronauts had completed some fun tests in space. One of them was lighting stuff on fire – for science! The wanted to see how fire behaves in space and discovered that fire burns at a lower temperature and needs less oxygen. It also burns with no flame in microgravity, explained Forman Williams the leader of these experiments: “the most surprising thing we’ve observed is continued apparent burning of heptane droplets after flame extinction under certain conditions. Currently, this is entirely unexplained.”
