In San Valentín there is breathed love or what is the same thing, "the love floats in the air". Of there the creative concept "Love is in the air", title degree of a famous song that evokes happiness, euphoria and "good roll". To execute the concept only we had to achieve that really the love was flying for the air. How? Sending messages on line in hot-air balloons. Hereby, to say that "Already I do not sit anything for you" we order a globe that it exploits and it can only totally empty, or to say that "Every day I want you more", we send a globe that swells up itself and it swells up itself until it is on the verge of longing. This way up to a whole of 6 creativities. Definitively, thanks to this concept the love surrounds us: we might say that "Love is in the air, but also On the Web!"
