Query: SADLY...IT DOESN'T WORK

I tried to prank a friend on a flight halfway across the country with this "fart candy," thinking what better way to use this joke than on a crowded plane. I tested it on myself first a few days before the flight and after 8 hours I had farted only once which is much less than normal for me. I tried it on my friend and his wife for an entire weekend anyway to no avail. Great idea, but it doesn't deliver.
