Coca-cola  Coca- cola is enjoyed all over the world. 1.6 billion

gallons are sold every year, in over 160 countries. The drink was invented by Dr. John Pemberton in Atlanta, Georgia, as a health drink on May 8, 1886, but it was given the name Coca-cola by his partner, Frank Robinson. In the first year, only nine drinks a day were sold. The business was bought by a man named Asa Candler in 1888, and the first factory was opened in Dallas, Texas, in 1895. Coca-cola is still made there. Billions of bottles and cans have been produced since 1895, but the recipe has been kept a secret! 

Diet Coke has been made since 1982 and over the years many creative advertisement have been used to sell the product. It is certain that Coca-cola will be drunk far into the twenty-first century.

The history of the hamburger  The hamburger is eaten more than any other food in

the world. The first hamburgers were made and sold in Connecticut in 1895 by an American chef named Louis Lassen. Louis called them hamburgers because he was given the recipe by sailors from Hamburg, Germany. Hamburgers became a favorite in the United States in the early part of the twentieth century. Their popularity grew even more after the Second World War, when they were bought in large quantities by teenagers who preferred fast food to family meals. In 1948 two brothers, Dick and Mac McDonald, opened a drive-in hamburger restaurant in California. Since then over 26,000 McDonald’s restaurants have been opened worldwide and now 35 million McDonald’s hamburgers are eaten every day in 120 countries around the world
