Do you remember those “glow-in-the-dark” watches of days past? How about the liability trial of the “Radium Girls” in the 1930s? Well just forget those dangerous days of using Radium, as there is a new player in town, at least to the gadget game. Tritium, a radioactive isotope of hydrogen.
The best feature tritium is the fact that it is safe, at least for now. It also allows your keychain to glow for approximately 10 years, making it all the more difficult to loose your keys. Available in a choice of a white or green glow.
