To turn the heat up on Butterkist microwave popcorn, we used OOH sites around the country in a completely new way. They became massive virtual microwaves complete with the satisfying sound of the corn popping inside the bag. We targeted transport hubs across the entire UK, stopping commuters in their tracks. The full motion video transfixed them with the ASMR-esque sensory experience of revolving bags of popcorn, and invited them to Go Grab the Butterkist.
