NASA’s Glenn Research Center in Cleveland has selected winners of the 2018 Microgravity Expulsion from Water Experiments Challenge.
Students who participated in the challenge designed and built objects that sunk in water in normal gravity, but were expelled from water during a free fall from Glenn’s 2.2 second drop tower.
The 2.2 Second Drop Tower allows experiment packages to free fall a distance of 79 feet (24 m).
