I went to a training class for work today (day 1 of 3), and found something from my childhood. Of course, as with so many of these things, we wrote of big pages of flipcharts and all that fun stuff. But the cool thing was:
WE HAD SMELLY MARKERS!!!!
That's what we always called them when I was in grade school, anyway. They were color-coded, scented markers. Red (cherry) is still my favorite, and keep the black (licorice) away from me.
Just thought I'd share.
