NASA Glenn Shows Students Temperature-Cooling Technology

Water is essential for life, and it is an important engineering tool as well. On March 21, NASA’s Glenn Research Center staff joined Great Lakes Science Center in celebrating World Water Day at the science center, home of the NASA Glenn Visitor Center, in downtown Cleveland. Staff conducted hands-on demonstrations highlighting NASA’s Liquid Cooling and Ventilation Garment during the free day for students.
