Bompas & Par were responsible for this ice cream for Cornetto stunt in London, making everyone's mouth and sometimes face light up when the main lights were dimmed.
Before going into the theater, people were given Cornettos to enjoy while taking in the film. Upon getting into the movie theater, most individuals started to happily munch away on their treat, only to soon find out that their mouth was glowing just as much as the person beside them. All reactions were captured on camera, and a few near misses when people went to lift the desert to their face (which is far more obvious when eating glow in the dark ice cream).
Bompas & Par successfully drew publicity to the company with this stunt.
