A flea is a very small and troublesome insect that can drive a dog crazy with all the itching and scratching it causes. So what do fleas have to do with markets and shopping? No one is quite sure, as the origins of the term 'flea market' are not certain. Some people believe it originates from the Dutch language, others think it stems from French. But there is one thing that almost everybody agrees on: there's no better place to shop if you are in search of a good bargain.

There are countless flea markets all around the world, and they are especially popular in Europe. One of the busiest markets in Europe is in the town of Lille, Northern France: La Braderie. With two hundred kilometres of open air stalls, this flea market offers a massive diversity of things to buy at reduced prices. Unfortunately, this amazing event, which has over a million visitors, is only an annual event which happens during the first weekend of September. Another shopper's paradise is in Russia. Moscow has many flea markets but the Vernisazh flea market at Izmailovsky Park is perhaps the most famous. There is almost nothing that you can't find there, especially if you are a tourist looking for authentic Russian souvenirs to bring back home.

But flea markets are not just places where tourists can buy inexpensive things. The Annex Antiques Fair and Flea Market in New York, USA, is a trendy market which has been attracting famous Hollywood stars as well as people living in the area ever since it opened. So, as you see, flea markets offer something for everyone!

On July 2nd 1900 crowds of people living in a German town gathered to watch the very first Zeppelin airship go up in the air. Similar airships had been around for about 50 years but the Zeppelin was the first airship with a special design that allowed it to travel faster than those built before. The Zeppelin's inventor was Count Ferdinand von Zeppelin. In 1910, the airship Deutschland became the world's first commercial airship. By the start of World War I in 1914, German Zeppelins had travelled over 172,000 km and carried over 34,000 passengers and crew safely.
