Usain Bolt races on a zero-gravity flight and defeats his two challengers. (0:26)

BUSSY-LETTREE, France -- Was it a bird? A plane?

No, Usain Bolt's latest publicity stunt.

The eight-time Olympic gold medalist took a zero-gravity flight over France on Wednesday, courtesy of a champagne producer.

Taking a break from his efforts to become a professional soccer player, Bolt said he felt like a "kid in a candy store'' after spending about four minutes floating and joking around in near-weightless conditions.

Aboard the Airbus A310 plane, the 32-year-old Jamaican caught a free-floating globule of champagne in his mouth and ran in low-gravity conditions.
