Milk of magnesia is a saline-based laxative that can treat constipation, as long as there's no indication of a bowel obstruction. The saline in the milk of magnesia works like a sponge when it hits the colon, drawing water into the area to soften the stool and ease its passage.
Floating Eggs. Eggs can float in water when the air cell has enlarged enough to keep it buoyant. This means the egg is old, but it may be perfectly safe to use. Crack the egg into a bowl and check for an off-odor or unusual appearance - a spoiled egg will have an unpleasant odor when you break open the shell, either when raw or cooked.
Place your egg in a bowl or glass of water- fresh eggs DO NOT float! One of your very own farm fresh eggs will sink to the bottom and lay on the side. Older eggs will sink to the bottom, but may stand up a bit. As long as the egg stays on the bottom, it is fine to eat or cook with. The Shake the Egg Test.
