Every year, grade school students gather at Nasa’s Wallops Flight Facility in Virginia to send science experiments into space. Now, these experiments have to be tiny, fitting into a 6×6 centimeter cube, which can either be flown into space in a research rocket or a scientific balloon. After the cubes are brought back to Earth, the students get together to analyze their experiments and see what happened while they were floating up there for 15 or so hours. This year, hundreds of students from the U.S., Canada and Colombia were in Virginia showcasing their experiments.
