AMSTERDAM (Reuters) - Scientists are using the Netherlands' largest football stadium to model how a cheering football crowd might spread aerosols through the air by spraying fine droplets, made to resemble saliva, over the empty stands.
Their hope is that by finding out more about the behaviour of aerosols or airborne particles, which could spread the coronavirus within a crowd, they will be able to remove them from the air and get fans back into stadiums and concert halls.
