Arizona State University's Open Door held its finale at the Tempe campus on Saturday, where visitors learned from ASU experts on a veritable smorgasbord of cool topics, including medieval armor-making, how earthworms help a compost pile and what nanotechnology means for the future.
Guests navigated obstacle courses with the Arizona National Guard, said hello to crawling spiders at the School of Life Sciences, watched glass-blowing demonstrations, hung out with Sparky and more.
From the world of space exploration to the cutting edge of sustainability solutions, the event gave thousands of attendees a look at the colleges, schools, programs and student groups that help make ASU the most innovative university in the country.
