'Cloud' Ads Float Sky-High

Forget blimps. A new kind of advertising sends company logos sky-bound in the form of clouds themselves—or almost. “Flogos” are flying, cloud-like shapes created from a soapy mixture pumped up with helium and other gases. The floating messages, sent up by repurposed snow machines, are completely safe, both for the environment and for passing airplanes, the inventor assures LiveScience.

"It does not pollute the skies," he said, and flying through one is just "like going through a cloud." The snow machines let off one 2-foot-by-1 flogo every 15 seconds. They normally rise to between 300 to 500 feet, and last from a few minutes to an hour. The creators and their company, SnowMasters, rent out the machines from $2,500 a day. (More advertising stories.)
