WHY A WINE BOTTLE’S BOTTOM IS CURVED.

There is much more important leason for the dimple in the wine bottle than the usual idea of the wine purchaser, who feels that the manufacturer of the wine has used a bottle so that it will not require as much wine to fill it. The real reason is that wine cools more quickly, and the temperature of the entire bottle is made more nearly equal if there is a dimple in the bottom than if there isn’t one. And a scientist has discovered that what works well in cooling will have precisely the same effect in heating, so that if a person desires to have a kettle or saucepan that will heat water more quickly than is ordinarily to be obtained, all that is necessary is to make a depression in the bottom. The discov erer of this fact has asserted that a quart of water may be boiled from the flame and heat of a burning newspaper if the water is placed in a covered vessel with an indented bottom.
