The next time you look up at the sky and see a cloud that looks like Mickey Mouse or your favorite fruit，look again. It may not be a cloud，but a Flogo-a logo that flies. It's a new form of advertising in the sky that's never been used before. It's a different way to market your products，logos，and events.

These funny logos are made with soap bubbles mixed with a little helium（氦气），which makes them lighter than air and float in the sky. Special machines are used to make these new funny Flogos. The machine, which can be rented for $2,500 a day, can make a Flogo every 15-25 seconds.

Flogos can fly much higher or lower if needed. They can last from a few minutes to an hour anywhere in the sky, depending on the weather conditions. Though they can fly up to 20,000 feet, they usually float around at 300-500 feet. Flogos are only white now, but people hope to have more colorful Flogos in the near future.

Flogos are green, 100% environmentally safe, because the soap used to make the Flogo comes from plants and leaves. So this fun way of advertising is healthy and good for the environment.
