What will protect a egg to drop 10 feet on conrete?

neglect the gravitational force

The non scientific way of protecting an egg all depends on what kind of egg, where you got it from, and how big it is. The best way to protect it is to make sure lots of leaves are on the ground under it, making it so that when it falls it's landing is softer and easier. If the egg for instance where a chicken egg, not store bought, small farm raised, then you could through the egg at full force across the yard, with no trees and when it lands on the ground, it won't brake. Store bought eggs will crack, only because they get less nutrition then farm raised eggs making the shells less strong and more breakable.
