I always have something in my wallet.
Last time I performed Powerball 60 after dinner, it was a huge hit.
The spectator asked me to read her mind without any props.
I told her to think of a number between 1 through 10.
I guessed 7 and I was right.
It was risky but I read that 7 is the most common number thought of if its done quickly.
She freaked out.

I always borrow a quarter of if anything you can perform a sponge ball routine with napkins or pieces of paper. Ask to borrow a bill and maybe perform a bill change? There are also a lot of mentalism things you can do that require no props.

I once did a Free Will style mentalism routine at a restaurant with some friends when they asked to see something and I didn't have anything on me. I just used objects from around the table and a prediction written on a napkin, incorporating some eq******e tips from a Max Maven lecture I'd attended not long before. One of my friends says it's her favorite effect of mine she's seen.

I did a bit of research and discovered I have sent out 83 free copies of my ebook, 'Sleight and the Family Stone" filled with effects, sleights and logic for performing
with "found objects" in natural settings -- exactly what this thread is about. The "cost" for the dozens of effects was a commitment to feedback -- pretty simple.

Amazingly, only 27 magicians actually met their commitment and responded at all after reading the material -- less than 1/3.
Of those, six said they couldn't understand it without a DVD to watch or found the text contained too many terms they did not know (Definitions in the Appendix)
What's the old saying? "Anything new but not for the first time!"

Only four (4) people responded as to ever performing any of the effect -- with wonderful results. Maybe others did and claim it as their own.

So, I conclude that most magician like carrying props and gimmicks around with them hoping to be called on to "do a trick." It is only lip-service to be able to perform magic effects with found objects.
You only have to master about six techniques in order to perform hundreds of effects with nothing in your pockets. Of course, presentation skills are a must. Maybe that is the problem.

What bothers me is the question of why a spectator should trust you and give focused attention if you can't meet a commitment to a fellow magician?

Oh yes, "doing tricks" doesn't require any trust, does it? There must be some kind of security in having props in your pocket. Where do you keep the magic?

I am having fun thinking through what can be done with Greg Rostami's Iforce app. If you have a phone on you - and who doesn't - you can do any-time miracles. What I most like is that the phone is just a tool - the place where your note app is. That way the attention is on the effect, not on something "magical" that happens on or in the phone itself. And since you can force up to 8 "choices", you can adapt it to a lot of existing routines. I think it's genius. And it's cheap. What's not to like?

And, of course I have to like Coffeehouse Conjuring material, since Greg and I spent a year coming up with the material (plus about 100 effects that never saw print). Hate to think all that time sucking down overpriced Java at the local Starbucks wasn't useful...

This reminds me of the time (1960s) when I a co-worker kept asking me to 'do a trick'-'do a trick'- almost everyday- SO - I asked him for a quarter - then I did severl slights and after- put the .25 in my pocket - when he objected - I said "I don't do magic for free" - no more bother-- Always wanted to do this with a Dollar bill-(the break a pencil bit - but didn't have the nerve nerve) L-O-L Ralph(russo)Rousseau

I always have my ring on so I do ring thing by David hauss to start of with then do some slights with my ring and I always have extreme burn 2.0 locked and loaded and Scotch and soda on me I keep them both in the wallet thing supplied with extream burn 2.0 locked and loaded

I ask them to pull my finger.

I ask them to take a coin from their pocket and out it on there palm... Then I instruct them to put their other hand over it....I don't go near them and wav my hand over there cupped hands and the coin vanishes from their hand into mine....and yes only one coin is used...

Sleepy

Just do my 10S Star Sign Divination and Tequila Hustler =)

Anything with in gimmicks coins. I love coin work

Heads or tails or which hand with imaginary coins.
Beat me on those ones!

Ask for 2 hair bands and make them appear the link together, disappearing saltshaker, make a coin disappear with a table napkin, the classic illusion of pulling your finger off but it's really your thumb.

Paper balls over head. Sponge napkins

The one tool I almost 100% of the time have on me is a TT. With that, and a few of the other miracles people have shared on this thread, you can perform any time, anywhere.

If I am at a restaurant, I will usually perform a Vanishing Salt Shaker and Stirring silver from J. Sankey.

X-finger

With no props on me, the best I do are math based stuff, 1089 being my favorite.

With no props, 37 force, psychological subleties (geometric shapes), Max Maven's Multiplicity and Alain Nu's Signagram.

Greg wilson on the spot has many great routines.
As well as paper ball over the head and Banachek's PK Time .
