Knowledge =/= Understanding
I was tying my shoes the other day, thinking about all the mechanics my hands are doing for this really mundane task, when I remembered about this video.
Premise: guy tries to ride a backwards bicycle. Turning right turns left, and turning left turns right. It takes him 8 months! His 6 year old son does it in 2 weeks. And when he tries to switch to a regular bicycle, something weird happens.
Favorite moment: his son has almost got it, and the dad gets this mad scientist voice and says "Get up, you got it!" :)
