Urticaria is also known as 'nettlerash' or 'hives'. It consists of wheals-spots or patches of raised red or white skin-each of which usually clears away in a few hours, to be replaced by other fresh wheals. The wheals are usually itchy, painful or cause a burning sensation.

The History of the Ferris Wheel. The Ferris wheel may be one of the greatest inventions of all time. It turned 100 years old in 1993. George Washington Ferris, a civil engineer from Illinois, invented the Ferris wheel in the 1890's. The first Ferris wheel was built for the 1893 Chicago World's Fair in 1893. The total Cost of the wheel was $300,000.00. Mr. Ferris' invention was and still is the largest wheel ever built. It weighed 1,300 tons (that's about how much a herd of 2,000 dairy cows would weigh !). The Ferris wheel stood 25 stories high and held over 1,400 passengers.
