The banquine act showcases the amazing agility of the human body. In this act, 15 performers (all Slavic) perform spectacular sequences of acrobatics and human pyramids, astounding audiences with their perfectly synchronized movements.

The final act of Quidam is the Banquine, an incredible balancing and acrobatic act involving the whole troupe. Banquine is an Italian acrobatic tradition that goes as far back as the Middle Ages. The literal definition of the word is "to bend". The acrobatic disciplined is traditionally executed at ground level by two carriers who, using their arms, catapult a flyer to stand on the interlaced hands of the carriers, a position called banquette. The impetus allows the flyer to perform acrobatic leaps and return to the starting point, the ground, or the banquette of a second team of carriers. For Quidam, the troupe toss each othr madly about the stage forming towers of four people high, and in daring jumps from one group to the other, landing only on the joined hands of the porter.

This act won a Golden Clown at the International Monte Carlo Circus Festival in 1999, and was seen on the big screen in Cirque du Soleil's IMAX film: Journey of Man. It is, perhaps, the signature act of Quidam and features performances completely unlike anything else.
