On October 19, about 1,300 visitors of all ages streamed through the gates of the Department of Energy’s SLAC National Accelerator Laboratory for a night of giant Legos, shock waves and stargazing.

The event, called Community Day, was filled with dozens of interactive exhibits, demonstrations and workshops. There were also engaging science talks, mini tours, refreshments and science-related giveaways.

Supported by 170 dedicated volunteers, the event was a collaborative effort between SLAC and the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), a joint institute of SLAC and Stanford University. Organizers were inspired to see the community come together as children and adults alike shared an evening of bubble-bursting, hair-raising, science-packed fun.
