I didn't realize how much of my knowledge of different LEGO bricks was connected to my sight, until I tried to put together a small LEGO police car in a blind build competition.
Now if you took away my hands and my sight -- I think I'd be in an even bigger bind. But that's not the case for a German teenager -- who comes to us courtesy of a television show in her homeland. She apparently can correctly identify Star Wars minifigures just by putting them in her mouth -- which considering LEGO bricks can be a choking hazard, I would not recommend trying at home.
I won't spoil how she does for you, but rest assured it's worth the four minutes and 36 seconds.
