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.
Truth: Poop shouldn't float. If you remember your middle school science, you know that anything denser than water is going to sink. If you notice your poop is floating every time you go, make an appointment with a gastroenterologist, says Raymond. This can be a sign that you're not absorbing fat and oil properly. However, occasional floaters are nothing to worry about. If you eat something that causes a lot of gas, it'll float, says Staller.
