Text №4 Clothes Washer

And you wonder why it is called the Stone Age. In the good old days, clothes were washed in a stream, by bounding the garments with rocks, stones and heavy sticks. Forget about soap - water was the sole cleansing agent. Fire added heat to the laundry mix, when clothes were washed in tubs with water heated over open fires and soap made at home from a combination of lye and ashes. Clothes were scrubbed on a corrugated board, wrung by hand, rinsed, then wrung again, and draped on lines or bushes to dry. Women's hands were freed by 1927, when wringer washers became standard, eliminating the washboard, open tubs and the boiler. A few "pumps" with the foot started the motor of the machine and kept it humming.

The first automatic washer - one that washed, rinsed and extracted water from clothes in one process - debuted at a county fair in Louisiana, in September of 1937. After World War II, the demand for washers was enormous. By 1953, automatic washers were outselling wringer washers ten to one. Today, washers offer a variety of features including a selection of cycles for washing different types of garments and water temperature and level options.

Text №5 Refrigerator

The earliest method of refrigeration was the storage of food in caves and cold springs. This method of storing food in cold places slowly evolved, as people began keeping food in their cellars, in their outdoor window boxes, in the snow, or underwater in nearby lakes, streams or wells. The invention of the icebox led to more efficient refrigeration. Ice was delivered to houses by delivery men and was used in wooden iceboxes that were lined in tin or zinc and insulated with sawdust or seaweed. The use of ice for refrigeration continued until World War I, when mechanical refrigeration came on the market. The first electric refrigerators with freezer compartments came on the market in the 1920s and 1930s. However, the mass production of refrigerators began after World War 11, when researchers had been able to successfully adapt large refrigeration systems for use in homes and shops. In the 1950s and 1960s, the invention of automatic defrost and automatic ice makers further improved the efficiency of refrigerators. Refrigerators also became available in a wide variety of size, color, and design.

Ice cream cone

For folks who lived anywhere near St. Louis, Missouri, the biggest event in the summer of 1904 was the Louisiana Purchase Exposition, which took place in that city. No one knew beforehand, but that exposition was the occasion where ice cream cones were first made and sold. The person who did it was named Charles Menches and he was a seller of ice cream. But he didn't plan to invent the ice cream cone. This is how it happened. Charles Menches sold his ice cream in dishes the way every other ice cream man did. That August when the Louisiana Purchase Exposition was at its height, was a real scorcher, however, and one day disaster struck Mr. Menches. There were so many hot and thirsty fairgoers wanting ice cream that he ran out of dishes. And it wasn't even noon. He had more than half a day of business ahead of him and not a single dish to serve his ice cream on. What did Menches do? He looked around him and thought fast. Nearby was a stand where his friend, Ernest Hamwi, who was from Syria, was selling a Middle Eastern treat called Zalabia. Zalabia consists of a crisp, wafer-like pastry sold with syrup. "Give me Zalabia!" cried Menches. He rolled up the Zalabia, scooped his ice cream on top, and presto! Ice cream cone was born.
