You've got some real money in your pockets, some billets or business cards, and a clean deck of 52. What's your go-to trick?

HaLo Aces

Although I don't have a deck in my pocket - done with "someone's" deck.

I carry a half-dollar for just this situation. I do a one-coin transposition followed by a vanish. I don't know what it's called, but it was taught to me by Ben Earl. It's short, hits hard, and I'm done being a dancing monkey in as little as one minute.

If you have nothing at all in your pockets you can still perform Invisible Dice. Best to do this for someone over 40 years old...I find younger than that usually can't accurately multiply a single digit by five without using a calculator...never learned multiplication tables!

My "go to" impromptu/casual material is suggestion based. Generally I start by handing them an imaginary ball and jazz from there depending on the reactions.

Except LarryD, when I'm asked to "do something" --- it's "something" with cards they want to see. Always. And they usually have a deck to stick into my hands.

My go to is Wikitest by Marc Kernstein. It's an amazing app.

With cards, I do two things, depending on what I feel like. Either I use a p**k and then pretend to read body language as I divine the card chosen (Ian Rowland has some very good work on this and demonstrates it beautifully in his Penguin lecture) or I tell a fortune. Some people are bothered by fortune telling, but most find it at least interesting.

I don't do money tricks and haven't ever really worked on b*llets the way I intend to.

I do have a necklace I wear especially so I can do some ring and string stuff, but that wasn't what you were asking.

I always carry "What tha" for impromptu situations. I also have a "mechanical" $1 to $20 bill in my billfold at all times. For cards ( with their deck) I'll do a simple force, double lift, not your card?, another wrong reveal, and finally their card is on the table under their hand. I also have a 3 card monte in my wallet, which I only do on occasion because the reveal is a little boy with his "watchamacalet" exposed. Great for a little impromptu bar magic.

Extreme Burn. Always in my wallet.

Do something with my peek wallet.. Allways a winner

If someone asks me to do a trick, I turn down the request. I don't want to waste time doing tricks, and I perform when I decide to not when a random persons wants me to.

P!

Ummm, I think you have mistaken me for that dude who is taller than me with the blue skin.

My go to impromptu effect is a trick I created called The Social Prediction. It just requires a phone and I do a killer confabulation routine with it

But if I were to just use billets like you said, I would perform Marc Spellman's Voqued routine.

"Someone asks you to "do a trick." What do you do?" I don't, as I'm not a trained monkey

However, if I'm in the mood to perform on the spot and without my own props, I'll look for what's around to do something. There is always something I can work with like coins, bills, napkins, silverware, water bottles, cards business cards, pen and paper, whatever happens to be handy at the time.

Mentioned this many times befor- after being asked to do a trick (too) MANY TIMES- ask for a coin- do an effect - then put THEIR coin in YOUR Pocket, if they ask for it or why - say "this may be my living - my family thanks you" -

If I happen to have a deck of cards on me, which I usually do, I'll usually do some sort of ace production. I also enjoy the simple scarf through someone's cell phone trick, as long as the audience trusts me enough to hand me their smart phone!
