Why horizontal egg can't break between two hands?

-It will break eventually if you apply enough force. It's just that when applied end to end a much greater force is required than when applied to the side.If you can maintain equal pressure around the egg, the shell is remarkably strong and won't break.



It is hilarious when the egg slips a little so the pressure is not equal all around. My sister got a face full of raw egg when the egg slipped in my dad's hands during his one and only attempt to prove the strength of an eggshell.
because of its shape. its shape allows it to take more force.
