Does a boomerang return when thrown in zero-gravity? Japanese astronaut Takao Doi did the experiment aboard the International Space Station:
Before he flew on the U.S. shuttle Endeavour to the International Space Station on March 11, astronaut Takao Doi told the press he wanted to test the boomerang in space. The idea came to him by request from his friend Yashuhiro Togai, a world boomerang champion. Doi has completed the test as promised and claims the boomerang worked well at the International Space Station.
A spokeswoman for the Japan Aerospace Exploration Agency told the Japanese daily Mainichi Shimbun that astronaut Takao Doi threw a boomerang and watched it come back.
Takao Doi told his wife in a chat from space that he was very surprised when the boomerang came back. He said it flies the same way it does on Earth.
