A replica of a condom-shaped balloon, the "Condomfiere," is set up at the Palais de la Decouverte on Jan. 26, 2010, in Paris as part of a campaign created by the French association CondomFly. The 40-meter-high Condomfiere will fly on every continent starting next Dec. 1, the World Day against AIDS, to promote condom use and prevention against sexually transmitted diseases.
