Wow, I never knew that!

The next time you pour your self a nice cold beverage and add a cube or two of ice you should be grateful that it floats because if it did not life on earth world not be possible. Every other liquid becomes denser and sinks when it freezes except for water, which becomes less dense and floats. If this were not true then when water froze it would sink to the bottom of the oceans, seas, rivers and lakes. As the freezing process continued, it would continue to sink and eventually the oceans, seas, rivers and lakes would be completely frozen solid. This would result in the death of all living creatures in the water thus making life on earth impossible. Aren’t you glad that water does not follow the normal pattern of liquids and does in fact float which guarantees that life continues as we know it and it means that it is possible to be hit on the nose by an ice cube when drinking a cold beverage?
