That was cool
Really cool

Nice!!! I am going to try it ☆

i love cool stuff like this

glad you guys like it.

the cool thing is that when tshtf the items will mostly be overlooked by scavengers and looters...so they should be available almost anywhere

Nice one! -

I wanna see if that potato will put enough charge in a mobile phone for 1 call , I think possibly more like 5 potato's over a couple of hours might do the trick.

I'm defiantly remembering the fire one though... Good job I'm no arsonist!! I can imagine CSI missing that cremated potato in the burnt out house

whats in the box?

Yeah, I did not catch what the label on the box was either, I am a little curious.

the box that he pours salt out of? it's...um salt

Nah he cheated... It was a box of granulated fire!

I'm gonna guess the reaction is between the toothpaste (alkali??) and the potato (acid?). And the salt is a catalyst and also acts as an electrolyte.

Or it could be the reaction is between the potato and the salt - and the toothpaste is more of a capacitor to hold a bit of charge.

Now you have fire what you really need is a recipe for a salty minty-fresh potato meal... Mmmmm.

Was just going to say! Dare you to eat it after making it! I bet it would taste amazingly harsh to the tastebuds!

Hey, great post! I have to tell you, I just tried it w/ some different items and as I guessed it did not work as desired, but I did get a little tiny charge out of it.
I used a russett potatoe, reduced sodium salt (LOL!!!) and aquafresh PASTE.
My g/f was like, WTF?!?!? LOL!!!

Star because I love stuff like this. Not the most practical thing in the world... but hella cool

Hey, that was really fun to watch!

Now off to find a potato and some other stuff. I just HAVE to try this for myself!

an even easier way with less steps would be to use a lemon

1. insert a steel nail into one end of a lemon
2. insert a copper coin 1/2 way into the other end of the lemon
3. wrap a section of wire around the nail
4. with another wire, put one end touching the coin and lightly touch the other end to the wire attached to the nail. You should see a small spark.

Very cool indeed. I just tried it and it works perfectly!

Thanks!

Cool One!

Questions:

Was the salt iodized?

Are both wires copper or is one copper and one some other type?

Does the toothpaste have to be the clear gel type or can it be the white pasty kind?

Thanks!
