That is interesting, because I once had an egg “explode”. But all it did was crack along the middle and gross smelling goo was leaking out. It was definitely not what I would call an explosion.The thought of an exploding egg is very dramatic. If can inspire fear. They can explode but what often happens is that they seep a foul smelling fluid when they go bad. Handle these eggs carefully, you sure do not want to break one, and get rid if it outside. Fear any egg that has the rotten egg smell.
