Watch astronaut Reid Wiseman create a levitating fireball in space


Astronaut Reid Wiseman on board the International Space Station recently uploaded a video of a fireball created by the FLEX-2 experiment. The fireball bursts alive and momentarily levitates until it quickly dissipates into a translucent sphere as it propels itself off into space.


This experiment is meant to explore future innovations to engine design.
