>Q: Why are raindrops shaped like tears?

A: The water molecules are polar, so they want to turn to the polar 
magnetic field of the Earth. But when the molecules begin moving toward the 
magnetic field, the Coriolis force makes them turn upward. In the southern 
hemisphere, raindrops look like upside-down tears.

>Q: Why does glass flow down old windows but not new ones?

A: Anything made out of glass is disturbed by waves at its resonant 
frequency. In old windows, the resonant frequency was often the same as the 
frequency of sunlight. New windows are designed not to have this problem.

>Q: Why are eggs easier to balance on the day of the equinox?

A: At the summer equinox, the Earth is at its closest point to the Sun. 
This means that the Sun and the Earth pull on the egg in precisely opposite 
directions. The forces from the Earth and Sun cancel each other out, so the 
egg has zero angular momentum.

>Q: Why is our galaxy expanding?

A: The stars in our galaxy are close enough together that once in a while, 
one star passes in front of another and blocks its gravity. Every time this 
happens, the galaxy expands a little.

>Q: Why does tapping the side of a pop can keep it from frothing over when opened?

A: Pop cans explode because the carbon wants to get out of the can. When 
you tap the can, some of the carbon hits the side of the can and combines 
chemically with the aluminium.
