Ever used a boomerang? It is a cool thing to play around. But, what about using a boomerang in microgravity? That's why, astronomers has decided to test it in the space. Japanese astronaut Takao Doi performed this boomerang test in space, during his free time on March 18 at the International Space Station. He threw a boomerang and it came back to him. Watch the video.
But, does it proves that boomerang will work in vacuum of space? Experts don't think so. Doi used a "Roomerang", a small, tri-blade boomerang intended for use in a small area. And in th pressurized environment of the ISS, microgravity has very little effect on the flight of boomerang.
