Virtual Experiments

Hack Month

In Fall 2020, Cal Hacks hosted a month long initiative to foster a love for creating and rediscover the fun in building for university students during the virtual semester.


In Spring 2020, Cal Hacks launched a global online hackathon to foster innovative and technical solutions to challenges faced around the COVID-19 pandemic.
