Scientists Discover What Happens When You Drop an Eyeball From a 5-Story Height

Compared to other exposed parts of the body, eyeballs seem especially weak and sensitive, and when it comes to getting scratched or poked, they are. If, however, you drop one from the top of a 5-story flight of stairs, you'll find the eyeball is surprisingly resilient — meaning it won’t land with a sickening splat. Instead, as Institute of Human Anatomy researchers Jonathan Bennion and Justin Cottle discovered, the easily squeezable ocular sphere will literally bounce. For their experiment, Bennion and Cottle used cow eyeballs, which are fairly similar to people’s peepers. Basically, the eyeball has three layers of fibrous tunics made of dense connective tissue. The strength of this tissue helps keep the eye looking globular when other forces try to ruin its shape. If you can get past the ick factor of the whole thing, watching it unfold might make you think better about your own eyeball’s ability not to crack under pressure.
