This animated TED Ed learning video is only about 4 minutes long and 6 million people have felt it was valuable to watch. I agree!

The transcript for this science video is available in 27 languages. Good to know!

About the video:  Whether we cry during a sad movie, while chopping onions, or completely involuntarily, our eyes are constantly producing tears. Alex Gendler tracks a particularly watery day in the life of Iris (the iris) as she cycles through basal, reflex and emotional tears.
