In July, 2012, the UW-MRSEC hosted graduate students from the University of Puerto Rico Mayaguez. While in Madison, Wisconsin the students performed their Science on Wheels (Ciencias en Ruedas) show at the Wisconsin Institutes for Discovery on the UW-Madison campus. The show teaches students about chemistry and physics using loud, exciting, highly visual content including explosions, water cannons, liquid nitrogen balloons and more. The Science on Wheels show was covered by the Wisconsin State Journal which averages 83,000 readers/day.
