The light turned yellow, just...

The light turned yellow, just in front of him. He did the right thing,stopping at the crosswalk, even though he could have beaten the red light by accelerating through the intersection.
The tailgating woman was furious and honked her horn, screaming in frustration, as she missed her chance to get through the intersection, dropping her cell phone and makeup.
As she was still in mid-rant, she heard a tap on her window and looked up into the face of a very serious police officer. The officer ordered her to exit her car with her hands up.
He took her to the police station where she was searched, fingerprinted, photographed, and placed in a holding cell.
After a couple of hours, a policeman approached the cell and opened the door. She was escorted back to the booking desk where the arresting officer was waiting with her personal effects.
He said, ''I'm very sorry for this mistake. You see, I pulled up behind your car while you were blowing your horn, flipping off the guy in front of you and cussing a blue streak at him. I noticed the 'What Would Jesus Do' bumper sticker, the 'Choose Life' license plate holder, the 'Follow Me to Sunday-School' bumper sticker, and the chrome-plated Christian fish emblem on the trunk, so naturally....I assumed you had stolen the car.''

Artificial snow

In 1946, artificial snow from a natural cloud was produced over Mount Greylock, Mass., for the first time in the U.S. An airplane spread small pellets of dry-ice (frozen carbon dioxide) for three miles at a height of 14,000 ft. Although the snow fell an estimated 3,000 feet, it evaporated as it fell through dry air, and never reached the ground. The experiment was carried out by Vincent J. Schaefer of the General Electric Company. Earlier the same year, he had produced snow in a cold chamber, on 12 Jul 1946.
