In Plain Sight

It’s idiom time! Thank you, once again, Merriam Webster:

I had an experience last week that reminded me of one of my favorite topics when I was in teacher mode, a unit about the limits of human perception…being unable to see what’s in front of us.  I don’t know how much fun the lecture was, but my students loved this video. 

Have you seen it already?  It’s just 90 seconds long . I don’t want to give anything away, so if it’s new to you…take a peek and then come back.
