Odd discovery – Post-Its glow in the dark.

I discovered that, under some conditions, 3M Post-Its glow.  They don’t simply glow, but they exhibit phosphorescence.  I did not expect that.

I discovered that basic 3×3 post it notes actually exhibit this when they are hit with my 432nm (bight blue) laser.  The exact Post-Its I used are here: http://www.amazon.com/Post-Notes-Colors-Sheets-654-14AU/dp/B0002DOC68/ref=pd_sbs_op_6
