Theoretically it seems like everyone should be capable of squirting milk from the eyes. After all, we all have nasolacrimal ducts, canals that allow tears to drain from the eyes to the nasal cavity. That's why people get "runny noses" when they cry. That's also why we should avoid touching our eyes: viruses on fingers can be transported from the eye via the nasolacrimal duct to the nose and throat (check out the very cool Common Cold website for more information). There are two nasolacrimal ducts - one for each eye - and each duct has two tiny entrances called lacrimal puncta. Using a mirror, look very closely at the inner corner of your eye and you'll see that each eyelid (upper and lower) has a lacrimal punctum. Normally fluid goes from the lacrimal puncta to the nose; eye-squirters somehow manage to reverse the flow.

It even possible for YOU to feel that channel in your sinuses. No, not with a an instrument or your finger as shown (Although, I heard of guy who's tongue was so long he could stick it up there.) You may have already felt it on a day, when you were very congested and your nasal passages were completely blocked up. When that occurs and you try to blow past that blockage, you might have felt or heard a tiny blast of air from the corner of your eye.
