From Digital Journal:

The Adler is hosting four Hack Day events in 2014 to connect science and technology communities in the city and reach youth with inspirational, hands-on science experiences. The first two events were held in April and the other days will be held at the end of May (Civic Hack Day) and in November (Girls Do Hack). Hack Days are designed for two main audiences: STEM professionals who are excited by technology and a curious and motivated youth audience.
