weired facts

• Clothes that are dried outside DO smell better because of a process called photolysis. What happens is this: sunlight breaks down compounds in the laundry that cause odor, such as perspiration and body oils.

• Clouds fly higher during the day than the night.

• Dirty snow melts faster than clean.

• Some early TV screens did emit excessive X-rays, as did computer monitors, but that was fixed long ago. Doctors suggest that at worst, sitting too close might cause some temporary eye fatigue—the same for reading with insufficient light—but no permanent damage, no matter what your mother claimed.

• A "fulgerite" is fossilized lightning. It forms when a powerful lightning bolt melts the soil into a glass-like state.

• STASI, the East German secret police organization, devised a devilishly clever way to prevent someone from giving them the slip during the Cold War: they managed to synthesize the scent of a female dog in heat, which they applied to the shoes of the person under surveillance. Then they simply had a male dog follow the scent.
