Glow in the Dark Filament!

So, when we received our new Cube, 3D Systems sent along some complimentary cartridges (in addition to what comes in the box).  One of the colors was Glow-in-the-Dark Neon Blue.  My students recently switched to that cartridge and I'll have to admit, it is pretty cool!  (Hard to photograph, though; it was truly a "shot in the dark"!)
