Many people might find it tricky keeping quiet through an entire roller coaster ride, but one Japanese theme park wants you to do that - and more.
Fuji-Q Highland near Tokyo re-opened last month after its virus shutdown.
It asked riders to avoid screaming when they go on its rollercoasters, to minimise spreading droplets, and instead "scream inside your heart".
And to encourage people to play along, it's getting riders to put on their most "serious face" for the ride photo.
They can share their photo online in the #KeepASeriousFace challenge, and those who do best will be given free day passes.
Here are some of the attempts:
The theme park will be running the challenge until 17 July, so if you're in Japan and can hold a serious face under any circumstances - now's your chance.
The no screaming rule - in addition to the mandatory use of masks - is meant to stop potential virus-carrying droplets from flying out of your mouth at 80mph.
Clearly, it'll be impossible to enforce this ruling - and according to executives who spoke to the Wall Street Journal, violations will not actually be punished. pgslot
