water
- Hot water weighs less than cold water for a given volume.Thanx Tony W
- There are more than 326 million trillion gallons of water on Earth
- If hot water is suddenly poured into a glass that glass is more apt to break if it is thick than if it is thin. This is why test tubes are made of thin glass
- If a glass of distilled water is microwaved, and then taken out upon which an additive is added, it will explode
