Try Zero G is a program run by the Japanese Space Agency (JAXA), which encourages young people to consider the impact gravity has on objects - and how experiments may differ when performed under microgravity conditions.
If your experiment is selected, it will be performed by Japanese astronaut Takuya Onishi, and high-definition video of the experiment made available.
