The manufacturers of our Glowrings, who produce military equipment and other need-to-see-at-night items, have taken this everyday nugget of basic science and made it their business. A Glowring is small enough and tough enough to attach to anything you might need to use in the dark, a bunch of keys being the most obvious. But because they can glow for up to a decade, you can leave them hanging off things that only come out once in a while like fishing gear and camping equipment. It does have to be pretty dark to see the glow, but that’s the point.
Sounds like £9.95 well spent if you tend to live the life of a night owl, retiring for the ‘night’ when the garbage trucks and street sweepers are starting to make their rounds.
