Each year, students from all over the world come to CERN as part of the CERN openlab Summer Student Programme. As well as attending lectures and working on their research projects, several of this year’s students decided to come together to take part in the recent CERN Summer Student Webfest, which saw participants hack their way through an entire weekend to produce a range of weird and wonderful science-related innovations. CERN openlab summer student Shubham Gupta tells us what it was like to take part in the event from the ‘Open Cosmics’ team. They were awarded the ‘Best Innovative Outreach’ prize for their work to open up data from cosmic ray detectors to the world.
