Microgravity

Pat Doty (right) of NASA/Marshall Space Flight Center (MSFC) demonstrates the greater bounce to the ounce of metal made from a supercooled bulk metallic glass alloy that NASA is studying in space experiments. The metal plates at the bottom of the plexiglass tubes are made of three different types of metal. Bulk metallic glass is more resilient and, as a result, the dropped ball bearing bounces higher. Experiments in space allow scientists to study fundamental properties that carnot be observed on Earth. This demonstration was at the April 200 conference of the National Council of Teachers of Mathematics (NCTM) in Chicago. photo credit: NASA/Marshall Space Flight Center (MSFC)
