04 / PAST EVENTS
THIS IS BIGGER THAN KOLKATA
some of the wild stuff Hack Club teens have done before.
Boba Bash is one tiny part of the Hack Club universe. these are four events that show the kind of energy we're talking about.
Undercity
a four-day hardware hackathon at GitHub HQ: 166 teen makers, 75 projects, 19 countries and 72 hours of making things that probably shouldn't exist.
see Undercity →
Parthenon
a three-day NYC hackathon with 126 teen programmers from 15 countries. 54 projects got shipped across 40 hours of building.
see Parthenon →
Shipwrecked
a four-day story-based hackathon on Cathleen Stone Island, where around 130 teens built projects while trying to survive their very fictional shipwreck.
