• This enormous sandpit is so large that it is almost the same size as Europe.""Can you guess which one it is?
• The nearest seaport to this sandy nation\s capital is more than 1,000 kilometres away.""No wonder they call it the Dead Heart of Africa
• It may seem hard to believe but this desert used to be much wetter and people lived here.""We know this because they left us these picturesque clues
• You may catch quite a thirst here but it is nothing compared to the driest place on Earth.""It has not rained there for more than 2 million years!
