A man named Mohammed Abelhameed Muqbel has set a new Guinness World Record for the largest stack of eggs which is THREE.
He identified each egg's center of mass, and then stacked them exactly so that they'd be able to stand end-over-end. To get the record, they had to remain stacked for five seconds, and all three eggs had to be fresh and free of cracks.
Mohammed has been teaching himself to balance things since he was six years old. He's 20 now.
