NASA astronaut Don Pettit assisted YouTuber Steve Mould in testing his 'weird chain theory' in space, aiming to understand how chains behave in microgravity, which could support Mould's explanation of the chain fountain effect. The experiment involved manipulating chains on the International Space Station to observe their movement without gravity's influence, providing some evidence that chains follow their own shape in space.
