Why, on some mornings, do I have to scrape ice from my front and back car windows, but not from the sides?
The most likely explanation is that the front and back windows of the car are more horizontal than the sides. When they lose their heat, it goes straight up into space, which means they cool down more than the side windows. Therefore, any condensation that forms on the front and back windows probably freezes quicker than that on the sides.

A Norfolk Island pine would be the best choice as a potted plant. The Norfolk pine is tropical and can be kept indoors through several seasons. Bring it out to the patio in summers. Check with a local florist or nursery for the best Norfolk pine varieties for your area.
If our body heat is 98.6 degrees F, why do we feel so uncomfortable when the outside temperature gets that high?
The human body is a little heat-producing engine, generating its own internal warmth. When the outside air is cold, our bodies do a pretty good job of producing heat to warm us up. But when the outside temperature gets to be as hot as 98.6 degrees F, we just keep producing heat. That's when we start to sweat, as a means of regulating our internal temperature. At very high temperatures, we have trouble giving off enough sweat to cool ourselves down.
Why are half-red/half-blue pencils called postal pencils?

Is the Christmas tree a Christian symbol? Where did it come from?
Decorated trees were used in winter celebrations long before the advent of Christianity. Plants and trees that remained green all year had a special significance for people who lived in cold-winter climes. Ancient people hung evergreen boughs over their doors and windows. Some believed that evergreens kept witches, ghosts, evil spirits, and illness away. Romans decorated evergreen trees with trinkets and topped them with an image of their sun god. Druid sorcerers hung golden apples and lit candles on oak trees to celebrate the winter solstice. It is generally agreed that the use of an evergreen tree as part of Christian Christmas celebrations started 400 years ago in Germany and spread to most of northern Europe by the 19th century.
When making meringue pie, should refrigerated eggs or room temperature eggs be used?
Use eggs at room temperature next time you make a meringue pie. Cold eggs cause problems in foam and sponge recipes because, when beaten, they do not increase in volume as much as warm eggs do. In general, all ingredients should be brought to room temperature (between 65 and 70°F) before baking.
