I think that ring trick plus Interlace would be overkill. Besides, don't you think the lighter trick would be STRONGER than Interlace? Think about it: Would you be more amazed if your ring vanished and appeared on somebody's shoelace or INSIDE a lighter that YOU were holding on to?

Wait, the person is holding the lighter? oh. hmm.... i suppose... just have to see how it all works out.

Well, not the whole time. Just at the time of the vanish.
I just took this from the description:

"The performer borrows a wedding band (or marked coin), wraps it in some tissue paper to 'clean it', then shows the spectator a really thorough way to do the job. The performer hands spectator his cigarette lighter: "It's a test of faith", he says. "Light the paper; the paper will vanish in a flash and your ring/coin will be more brilliant, more beautiful than you've ever remembered. Trust me".

Spectator lights paper, it vanishes in a flash, leaving ... nothing..... "O.K. - well at least I got the paper part right ..."

And then, after the obligatory hemming and hawing, performer discovers a rattle in his lighter. He pulls the lighter apart: INSIDE THE SOLID STEEL LIGHTER IS THE BORROWED RING!"

I wonder if you can use the case to an existing Zippo to replace the one it came with?

oooh, thanks duds!
Zenn: I don't know.

A little off topic for minute, how long does your Zippo stay filled? Because mine usually evaporates (the fluid, not the lighter) after a day or two and I don't like refilling it.

Well I like clicking it a lot some like a week?

I don't smoke... so...

neither do I lol (asthma) I just like playing with fire =]

Yep, I don't smoke but I'm a freakin' pyro!

i want to get one, i LIKE fire! haha! but unfortunately i can't buy flash paper, i don't see how it doesn't burn you anyway.

Why can't you buy flash paper?

Age or parental restrictions, I'm guessing.

I've smoked before (occasionally for a trick, like Derren Brown's Smoke), but Zippo's are useful props even without smoking. Frixion pen work, etc. You can do quite a bit with 'em.

No, not my parents, all though i don't know if they would let me:p it's because you aren't supposed to sell it to minors, according to sankey's website.

Hey I'm a "minor" and I use flash paper. I get it really cheap at a website (I don't know if I can say the name here).
