Rollerball pens are writing instruments which use ball point writing mechanisms with water-based liquid or gelled ink, as opposed to the oil-based viscous inks found in ballpoint pen. The characteristics of these less viscous inks, which tend to saturate more deeply and more widely into paper than other types of ink, give rollerball pens their distinctive writing qualities.

THE IMPORTANCE OF CORRECT TIRE PRESSURE
Driving with correctly inflated tires is important for several reasons:
• Increased safety
• Reduced treadwear
• Improved handling and ride performance
• Better fuel economy
The Tire Gauge Controversy-Saving Gas?
Barack Obama recently said that Americans should tune up their cars and keep their tires properly inflated to save gas. He said that doing so would save more oil than what would be gained by offshore drilling. The McCain campaign jumped on it and began handing out tire gauges marked "Obama Energy Policy".
at Various Altitudes
* Sea level - 14.7 psi
* 10,000 feet - 10.2 psi
* 20,000 feet - 6.4 psi
* 30,000 feet - 4.3 psi
* 40,000 feet - 2.7 psi
* 50,000 feet - 1.6 psi
If you've got a car, you probably own one of those pen-sized tire-pressure gauges. It's got a funny little spherical thing on one end and a little sliding scale on the other end.
A tire pressure gauge is a relatively simple device. See more tire pressure gauge pictures.
Have you ever wondered how it measures the pressure? And why doesn't the little scale just blow out the end?
In this article, we'll figure out exactly how these pressure gauges work!

How out of touch is Barack Obama? He's so out of touch that he suggested that if all Americans inflated their tires properly and took their cars for regular tune-ups, they could save as much oil as new offshore drilling would produce. Gleeful Republicans have made this their daily talking point; Rush Limbaugh is having a field day; and the Republican National Committee is sending tire gauges labeled "Barack Obama's Energy Plan" to Washington reporters.
