The student members of the American Chemical Society at the University of Tennessee at Martin (UTM SMACS) celebrated Earth Day on April 19. They made ice cream using liquid nitrogen as coolant, home-made recipe root beer using dry ice for carbonation, along with usual hot dogs and hamburgers. There were hand-on demonstrations for kids besides demonstrations of the THERMITE reaction, mentos in diet coke, etc.
