It didn't work for me - the video that is, I've never tried to light a fart.
My late husband used to tell me that it was a matter of great contests when he was at school - seeing how large a flame could be produced and for how long. This, along with other things he mentioned, always made me think I was rather glad I didn't meet him until he was a 20 year old airman. I don't think I'd have liked him very much when he was a small boy.
