An egg looks like a crazy jellyfish underwater

A cracked egg on land might make a big mess, but 18 meters (60 feet) below the surface of the ocean, the pressure on the egg is 2.8 times atmospheric pressure, and it holds it all together like an invisible eggshell. BIOS / Via youtube.com

That's because there's so much pressure on the egg (2.8 times atmospheric pressure), that the surrounding water sort of acts like an eggshell to keep the yolk intact, according to Live Science.

Pressure increases the deeper you dive. At around the two-mile mark (that's where the titanic rests), the pressure is 2.8 tons per square inch, wrote William J. Broad in the New York Times.
