Dry erase markers are amazing. No one will dispute the superiority to chalk- no dust, no mess, better contrast, etc. However, the real reason they are amazing is their ability to be used on glass- window and mirrors- as a means to leave messages! Think green! The possibilities are indeed amazing! Case in point- I recently had one of my classes meet at a different location on campus. We are forever being encouraged to save paper costs. Reduce, reuse- or don't use! This year I have gone almost completely paperless in my classes, so, my natural instinct is let's just write on the door window. Students see it as they approach the door and it is easily wiped off!

Sadly, the powers that be complained. Apparently it is proper procedure to print on paper and then laminate any messages. Even a one line message for one day.

Oxymoronic? You decide.
