It might be the unlikeliest instructional video ever, but footage of two Japanese amusement park executives demonstrating how to "scream inside your heart" to avoid spreading COVID-19 while on a rollercoaster has been a roaring success. The video features the executives, one in a full suit and tie, the other in a shirt and bowtie, sitting stiffbacked and straightfaced in silence, with only the only sounds coming from the whipping of the wind and the grinding of the rollercoaster.
