Fire From Potato ? Yes!

Girl: Can you light my cigarette?

You: Well, I don't have my lighter or matches... but wait! I have big pockets, so I carry around a bunch of junk. Let's see... Good news! I've got all the stuff to make a fire.

lol not the best scenario.
Cool experiment though...

Omgsh your so right! It's sooo much easier to carry around a sack of potatoes, tootpaste, salt, a spoon, 2 wires, 2 toothpicks, or better yet some duct tape, and some tampons.

now show us what you swapped into the potatoe to get the high voltage for a spark like that to jump across (high voltage capacitor?) when there's a cut in the movie, and you also forgot to mention that cotton swabs don't burn that nicelly all by themselves...unless they are soaked up in some flamable liquid (you can easyly notice how it bursts into flames all around before the cotton itself starts burning/melting)

I don't have a lighter but wait 10mins and I'll fire you up honey....nice job if it works

always have extra lighters, they're only like 39 cents for crying out loud lol

and successfully quit smoking in the time it would take this guy to light my cigarette. But, okay, cool. If I'm ever stuck on some island, and all I have are these random objects, maybe it'll be helpful.

i hold a chem degree and look at the chemisty behind this, it doesnt work!
u placed a current source in the potato!
stupid vid

It seems to be based off the idea that one can make a battery using a potato and two metals. The problem is

(1) both metals are the same --> no potential difference
(2) cotton does not conduct well enough to light on fire except at very high voltages
(3) even if the combination of toothpaste and salt did something, the system is symmetric -- which way would the current flow?

girl: do you have a light
you:no but i do have a pottato a spoon salt and more S**t just wait 10 minutes and i have a light for you
girl:yeah right
-10 mins. later-
you: here you go
girl: -sleeps-
you WTF you wanted a light right??
hehe 5 stars great

man, this is bullshit not science...

going out and buying a match box is too much easier , and it only works 1 time , but as a scientific experience , it's great

10 minutes for 5 second fire lol
nice experiment

...to light a fire, you need a potato, a knife, salt, 2 wires, toothpaste and cotton. Nice experiment but i prefer to carry an extra lighter or even some matches...

way to much SPARE TIME. how do u invent something like that?

this doesn't work man :( not to me

hi girls.. need a fire? hoo dam I dont have fire but I have potato? come on xD but this is cool anyway realy good 5 stars

Everyone's focusing on the girl and not the fire. XD

thants really neat and i want to do it for my science project but i dont know what kind of wires can you tell me please any one know if so please do tell i want to know for my science project please

i tried it...along time ago

this comments are so stupid.. how old are u guys??? cant you see that it is not the girl that is important. the thing is that the experiment is really cool, and this kind of videos is what metacafe is all about... grow up will you...

nice girls don't smoke. tell the dirty mole to F@$k off

it is a good idea. one question though...any toothpaste would work?? or only the jel type??let me know
