don't use destilled water, due to the low osmotic value of destilled/demineralised water it will rapidly flow into healthy cells of the embryo causing them to expand and burst. If by a small wonder that egg still has a chance I would use a boiled saline solution to inject into it. Saline has the same osmotic value as cells from living tissue so it will not destroy it... but judging from the picture I wouldn't say that egg still has a chance.
