laser pointer and a fluorescent lanyard

This is one of the coolest things I’ve seen all year! I have a habit of shining my 405 nm laser pointer at fun things. But I was really surprised when I donned my safety goggles and the beam hit this Chroma lanyard:

Wow! I think what’s happening is that the fibers are acting as light guides—like fiber optics. So you see the fluorescence travel along the fibers, which are weaved diagonally up along the strap, over the edge, then diagonally back down. Super cool. Chroma should use this for marketing.
