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.
Here are a few more simple ways to determine the freshness of your eggs: 1  Grade A eggs have a firm white, a small air cell at the wide end and a centered yolk. 2  A fresh egg will sink in water while an older egg will float.  In a fresh egg, the yolk sits up high, and the white is thick and closely surrounds the yolk.
