Answer: First is the lively debate over who started it. Was it at the World Cup Soccer competition in 1986, making it the Mexican wave ("La Ola")? Or at the 1968 Olympic games in Mexico City, or a major league baseball game? Probably Mexico City is correct, says Timothy Gay in "Football Physics."
Second most amazing is that three Hungarian researchers actually studied Waves at 14 soccer stadiums holding 50,000+ people. They found the Waves generally travel clockwise at 12 meters (20 seats) per second and are 6-12 meters (15 seats) wide. It takes no more than a few dozen participants to get a Wave going.

Answer: The official record was set in 1957 by Paul Anderson, a "back lift" in which he stooped beneath a reinforced wood platform supported by sturdy trestles, says Jearl Walker in "The Flying Circus of Physics."
Before him was a short stool against which he could steady himself and push downward, above him were auto parts and a safe filled with lead. "With an astonishing effort of both arms and legs, he lifted the platform the composite weight being 6,270 pounds!"
Answer: It's tiny ice crystals suspended near the ground as a mist or fog, says Randy Cerveny in "Freaks of the Storm." When warm air from a valley rises up into a cold wind blowing lengthwise, a freezing fog can descend and cover everything with minute frost crystals. A five-day pogonip the term coined by Native Americans of Nevada in January 1892 deposited a coating of ice 2 inches thick on trees, buildings, cattle, people! "I personally saw one in Antarctica in 1987. It appeared as a bright line of frosty white on the horizon and trekked across the flat ice sheet for several hours before reaching our camp. We were encased in a white featureless tomb."
