Spend an afternoon learning about science in a hands-on way and have fun doing it.

Check out the auditorium show “Colder than Cool,” where Fermilab scientists will explore the chilling effects of liquid nitrogen on everyday items and demonstrate its uses in electricity and magnetism.

Other presentations include “Physics and Engineering of Sports” and a panel on women in science. About a dozen scientists and engineers will be ready to answer questions in the exhibit area on the 15th floor of Wilson Hall.
