Terrifying video reveals how easily virus can spread in restaurants as diners unwittingly contaminate themselves within minutes

A Japanese 'black light' experiment proved how quickly coronavirus can spread in restaurants and other communal spaces by using fluorescent paint as a mock virus to 'infect' diners. 

 

The experiment, conducted by TV channel NHK, used paint to represent a 'virus' to show how easily infections can spread through communal facilities. 

 

One of the ten participants was chosen to be 'infected' and had the fluorescent paint applied to his palms.

NHK's video footage then shows the participants enjoying a 30-minute buffet before a blue light is turned on, revealing how far the 'virus' had spread.
