Nite Glowring Safety Markers

This is kind of cool - a glowing tube that doesn’t need batteries, and that you don’t need to “charge up” with an external light. It just glows all the time, all by itself, for up to ten years!

What can you use it for? How about an easy to find keychain? Body jewelry when you go clubbing. Use them at night when you’re camping. Put them on your kid’s clothes when they go trick-or-treating to make them more visible. Put them on YOUR clothes when biking at night - they are visible for up to 100 feet!

How it works: Each marker contains a small hollow glass tube, which has been internally coated with a phosphorous material, injected with a special gas and then sealed by a laser. The gas inside the tube excites the phosphorus, which creates a cold light that will glow for ten years without any external power source.      link
