This is the terrifying moment a Ferris wheel full of passengers went haywire at a carnival.<br /> <br />The attraction started spinning out of control and jolting back-and-forth at the show in Sakon Nakhon, Northeastern Thailand, on Sunday night (September 20).<br /> <br />Footage shows how the panicked operator climbed onto the 40ft high machine to try and bring it under control.<br /> <br />He's seen in the video scampering between the metal bars while trying to use his body weight to stop the movement back and forth.<br /> <br />Fairground-goers clung onto their gondolas as the normally placid ride changed into a white-knuckle rollercoaster.<br /> <br />The 'carnie' eventually managed to help bring the ride to a stop. He blamed a rainstorm earlier in the evening for interfering with the electricity cables.<br /> <br />Onlooker Graze Ze said there were no injuries from the fairground ride malfunction.<br /> <br />She said: ''The Ferris wheel started going backward then forward. When it first happened nobody knew if it was part of the ride. People realised it was a problem and it was pretty scary for those who were stuck on there.''
