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.
Why do clouds float in the sky even though they have tons of water in them?

The cycle starts when the Sun warms the Earth, which in turn, warms pockets of moist air.
