Fermilab Family Open House
Fermilab (Wilson Hall), Batavia, IL
Fermilab's Family Open House opens the Batavia particle physics laboratory's grounds to the public for one free day each winter, with hands-on physics demonstrations, tours, and a liquid-nitrogen show. More than two thousand visitors typically attend to see areas of the lab not normally open to the public. The event has run most years since the 1990s, usually on a Saturday in February.
That was 1 of the hidden places.
