Start in Goatville and go into the antigravity facility behind the gas station. There is a place where you can jump the fence or you can go through the hole in the fence behind the gas station, near a soccer goal. Break down the container walls and walk up the metal walkway to the left and enter the fan room. You can jump and remain suspended in the air inside the fan room. You can do as many flips as desired as long as you remain over the fans. Try to stay directly over the fan and away from the edges. After doing as many flips as needed, get your hooves back under you and guide yourself to the edge of the room. You must land correctly to earn the achievement. You can also land in the rafters or on the windowsill if desired.
