Make fire with potatoes, salt & toothpaste (FAUX-TO?)

Hotly contested video. The question remains, is the science behind the potato fire bonafide or bogus?

Cut a potato in half. Hollow out one side of the potato. Fill with a mixture of salt and tooth paste. Using toothpicks, poke holes to insert electrical wires into the other half of the potato. Assemble both halves and secure with toothpicks. Attach combustible material to one wire and wait 5 minutes. Connect wire. And...

You tell us. Fire in the hole?
