Derek Muller’s Veritasium project has produced a new video, “The World in UV,” together with Dianna Cowern’s Physics Girl, who has produced a video of her own—“Sunscreen in UV.” The videos are striking in their portrayals of UV phenomena such as normally invisible skin damage, dental crowns, and UV smog; the most visually arresting effect seems to be that applying sunscreen looks like applying shoe polish under UV. Fun was had creating UV-only visible graffiti with sunscreen, and discussing and assessing the SPF, function, and pollution of different reflective and absorptive sunscreens. The new UV videos are somewhat reminiscent of Michelle Thallers’ famous outstanding “Infrared: More Than Your Eyes Can See” video.
