German scientists decided to check how the coronavirus spreads at public events. They are recruiting 4,000 volunteers to go to Tim Bendzko's concerts in Leipzig. All participants must submit a negative test for COVID-19, Business insider reports.

There are three concerts in the plans:

in the first they will not observe social distance at all, in the second they will let people into the hall in groups, and in the third they will only allow seating at a distance from each other.

At all events, people will be wearing masks. Everyone will be given a fluorescent sanitizer to help scientists track which surfaces are touched the most..

The organizers of the experiment say that the current ban on public events is a threat to artists and athletes, because their careers directly depend on concerts and matches..
