#ISing Joy to the World is a new participative project that has brought together over 100 people performing "Joy to the World" at Science Museum CosmoCaixa.

The #ISing project has advanced even further and brought together over 100 amateur singers to create this Christmas video. Accompanied by both music and video production professionals, the participants worked over 3 weekends and this is the result.

On a special night, one of the museum's visitors presses a button and, suddenly, the magic begins.
