Glowing PLA...

After receiving my PLA from UltiMachine on Monday I put the natural roll on and did some test prints.  I was saving the blue translucent until after adjusting the machine a little more.  For some reason I thought "I wonder if either of these PLAs glows under black-light?"  So I dug out a black-light and tried, nothing from the natural but look what the blue does...

 This is very cool and as far as I know previously undocumented.  Here are some more pictures:

Also check out my video of this print on YouTube.  And if you like fluorescent materials you should go buy some of this very cool PLA.
