Just by seeing the ingedients he uses, you can already tell that its not going to work ... how would salt and toothpaste mixed together inside a potato and 2 wires start a fire ,,, it makes no sence ,,, however, out of bordem and the possiblity that it may work , I tryed. Twice lol haha and guess what it didnt big surprise there.... and for the guy that made the comment on the glass of 151 and the 100 dollar bill... That wont work either your bill would burn....It's rubbing alcohol and a little bit of water.. the alcohol burns off as the water preserves the paper...

It's a simple half-cell galvanic reaction. Essentially the potato and salt act like the inside of a battery and placing the wires together creates a flow of current with a combination of heat and a spark (that's why you wait 5 mins to "charge" up the cell. The cotton merely catches the spark and creates the flame.
