What's with the big head?

ANSWERS

Explain This

Anyone peeking out the window of this Swiss chalet would have gotten an eyeful of artist Vincent van Gogh's head. The head is actually a hot-air balloon. Like all hot-air balloons, the 30-meter (90-foot) tall head floats with the help of heated gas. Heated gas inside a balloon is less dense than its surrounding air, causing the balloon to rise. The giant head lifted off from the ski resort of Chateau d'Oex in the Swiss Alps on January 24, the opening day of tin international hot-air balloon festival. The big noggin was one of 130 balloons--including one shaped like a giant winged cow--that took part in the weeklong festival.
