After a successful launch and return of a rocket, NASA and SpaceX noticed a strange gel like substance on the wing. Under the microscope the strange thing has fibers, but no cells. When introduced to water the substance tends to move around. When exposed to warm temperatures it seems to grow in mass.

nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive
