How to Make Metal Rust With Potatoes

I've been working on a project that required me to make some nails and hardware rusty. I wanted to go the easiest route (of course) so I tried the vinegar and salt method which I had used before, but it just wasn't happening fast enough, meanwhile, my husband was chopping potatoes for stew: lightbulb!
The metal started to turn dark immediately and after soaking for about an hour, I took them out and rust began to form.
I let the potatoes oxidize for a while, then dropped them in a vinegar salt mixture.
I used standard nails - not zinc or galvanized
The rust really begins to form once exposed to air.

    Why for Pete's sake would you ever want metal to rust?
