This tool was designed by NASA engineers to demonstrate and teach principles of microgravity and its relationship to science and math. Teachers may perform a series of demonstrations to provide a visual, physical connection between free-fall and microgravity conditions and to understand why certain experiments are performed under microgravity conditions.
