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.
2. Place the egg carefully in the cup of water. You do not want to break it especially if itâs a bad egg. 3. If it floats itâs no longer good to eat. If it sinks and lies flat at the bottom itâs in good shape. The reason for this is the air pocket inside the egg.
