Black light experiment shows how quickly a virus like Covid-19 can spread at a restaurant
A viral video from Japan aims to show how easily germs and viruses can spread in restaurants when just one person is infected.
The experiment simulates the atmosphere at a buffet restaurant or on a cruise ship. It was conducted by the public broadcasting organization NHK in conjunction with health experts.
The video shows 10 people coming into the restaurant, with one singled out as the "infected" person. Each participant goes about the buffet as they normally would, not considering a potential contamination.
At the end of the video, the participants are cast under black lights illuminating where the "infection" has spread.
The substance, used to signify the germs, can be seen on food, serving utensils and platters, and even on the faces of some of the participants. Read the full CNN article here.
