NanoDays / MicroDays is a celebration of the small! Learn about nanoscale science and engineering through hands-on activities and demonstrations for kids and adults. You can also learn about other small-scale science, including microbiology in Yellowstone. Help build a carbon nanotube, try the electric squeeze, play with nanosand and get a nano tattoo! Come anytime between 5pm and 7pm. http://eu.montana.edu/nanodays
