No way its real. I used to squeeze orange peals into a flame to show people they were flammable which they are, but to a very small degree. The juice is what is flammable. Believe it or not I have tried lighting orange peals on fire with little to no success so I doubt this method worked. If you watch right before the fire starts the camera pans up and the guy holding the stick starts fooling with something in front of him and gives this "Alright i'm ready" look before the camera pans back down. I'm guessing they used something other than what they claim.
Why stop there, let's use a grapefruit to make a bigger fire
