Helmet from KFC.

KFC invented the Brainwave Bucket helmet, which analyzes brain activity. All for the sake of a promotion - to prove to customers that while eating chicken, the stress level is reduced. Participants are offered to watch an ASMR video with chicken cooking, and if the subject's brain activity does not change, the chicken will be given out for free. By the way, in the future such buckets will be sold to everyone.
